How It Works
Timestamp Online is timestamp converver between unix timestamp and human readable form date.
If you want to convert timestamp, it is sufficient to either enter your timestamp into input area,
or you can construct URL with your timestamp – your-timestamp}.
Timestamp Online also supports countdown, so you can see, how much time remains to particular timestamp.
URLs for countdowns have following form – your-timestamp}.

Unix Time
Unix time (also known as POSIX time or Epoch time) is a system
for describing instants in time, defined as the number of seconds
that have elapsed since 00:00:00 Coordinated Universal Time
(UTC), Thursday, 1 January 1970, not counting leap seconds. It is
used widely in Unix-like and many other operating systems and
file formats. Because it does not handle leap seconds, it is
neither a linear representation of time nor a true representation
of UTC.

Date.parse() – JavaScript – MDN Web Docs
The () method parses a string representation of
a date, and returns the number of milliseconds since January 1, 1970, 00:00:00 UTC or
NaN if the string is unrecognized or, in some cases, contains illegal date
values (e. g. 2015-02-31).
It is not recommended to use as until ES5, parsing of strings
was entirely implementation dependent. There are still many differences in how different
hosts parse date strings, therefore date strings should be manually parsed (a library
can help if many different formats are to be accommodated).

Parameters
dateString
A string representing a simplification of the
ISO 8601 calendar date extended format. (Other formats may be used, but results
are implementation-dependent. )
Return value
A number representing the milliseconds elapsed since January 1, 1970, 00:00:00 UTC and
the date obtained by parsing the given string representation of a date. If the argument
doesn’t represent a valid date, NaN is returned.
Description
The parse() method takes a date string (such as
“2011-10-10T14:48:00”) and returns the number of milliseconds since January
1, 1970, 00:00:00 UTC.
This function is useful for setting date values based on string values, for example in
conjunction with the setTime() method and the
Date object.
Date Time String Format
The standard string representation of a date time string is a simplification of the ISO
8601 calendar date extended format. (See the section Date Time String
Format in the ECMAScript specification for more details. )
For example, “2011-10-10” (date-only form),
“2011-10-10T14:48:00” (date-time form), or
“2011-10-10T14:48:00. 000+09:00” (date-time form with milliseconds
and time zone) can be passed and will be parsed. When the time zone offset is absent,
date-only forms are interpreted as a UTC time and date-time forms are interpreted as
local time.
While time zone specifiers are used during date string parsing to interpret the
argument, the value returned is always the number of milliseconds between January 1,
1970 00:00:00 UTC and the point in time represented by the argument or NaN.
Because parse() is a static method of Date, it is called as
() rather than as a method of a Date instance.
Fall-back to implementation-specific date formats
Note: This section contains implementation-specific behavior that can be inconsistent
across implementations.
The ECMAScript specification states: If the String does not conform to the standard
format the function may fall back to any implementation–specific heuristics or
implementation–specific parsing algorithm. Unrecognizable strings or dates containing
illegal element values in ISO formatted strings shall cause () to
return NaN.
However, invalid values in date strings not recognized as simplified ISO format as
defined by ECMA-262 may or may not result in NaN, depending on the browser
and values provided, e. :
// Non-ISO string with invalid date values
new Date(’23/25/2014′);
will be treated as a local date of 25 November, 2015 in Firefox 30 and an invalid date
in Safari 7.
However, if the string is recognized as an ISO format string and it contains invalid
values, it will return NaN in all browsers compliant with ES5 and later:
// ISO string with invalid values
new Date(‘2014-25-23’). toISOString();
// throws “RangeError: invalid date” in all ES5-compliant browsers
SpiderMonkey’s implementation-specific heuristic can be found in
The string “10 06 2014” is an example of a non-conforming ISO format and
thus falls back to a custom routine. See also this rough outline on
how the parsing works.
will be treated as a local date of 6 October, 2014, and not 10 June, 2014.
Other examples:
new Date(‘foo-bar 2014’). toString();
// returns: “Invalid Date”
(‘foo-bar 2014’);
// returns: NaN
Differences in assumed time zone
Given a non-standard date string of “March 7, 2014”, parse()
assumes a local time zone, but given a simplification of the ISO 8601 calendar date
extended format such as “2014-03-07”, it will assume a time zone of UTC
(ES5 and ECMAScript 2015). Therefore Date objects produced using those
strings may represent different moments in time depending on the version of ECMAScript
supported unless the system is set with a local time zone of UTC. This means that two
date strings that appear equivalent may result in two different values depending on the
format of the string that is being converted.
ExamplesUsing ()
The following calls all return 1546300800000. The first according to ES5
will imply UTC time, and the others are specifying UTC timezone via the ISO date
specification (Z and +00:00)
(“2019-01-01”)
(“2019-01-01T00:00:00. 000Z”)
(“2019-01-01T00:00:00. 000+00:00”)
The following call, which does not specify a time zone will be set to 2019-01-01 at
00:00:00 in the local timezone of the system.
(“2019-01-01T00:00:00”)
Non-standard date strings
If IPOdate is an existing Date object, it can be set to
August 9, 1995 (local time) as follows:
tTime((‘Aug 9, 1995’));
Some other examples of parsing non-standard date strings:
(‘Aug 9, 1995’);
Returns 807937200000 in time zone GMT-0300, and other values in other time
zones, since the string does not specify a time zone and is not ISO format, therefore
the time zone defaults to local.
(‘Wed, 09 Aug 1995 00:00:00 GMT’);
Returns 807926400000 no matter the local time zone as GMT (UTC) is
provided.
(‘Wed, 09 Aug 1995 00:00:00’);
zones, since there is no time zone specifier in the argument and it is not ISO format,
so is treated as local.
(‘Thu, 01 Jan 1970 00:00:00 GMT’);
Returns 0 no matter the local time zone as a time zone GMT (UTC) is
(‘Thu, 01 Jan 1970 00:00:00’);
Returns 14400000 in time zone GMT-0400, and other values in other time
zones, since no time zone is provided and the string is not in ISO format, therefore the
local time zone is used.
(‘Thu, 01 Jan 1970 00:00:00 GMT-0400’);
Returns 14400000 no matter the local time zone as a time zone GMT (UTC) is
SpecificationsSpecificationECMAScript Language Specification (ECMAScript)# rseBrowser compatibilityBCD tables only load in the browserCompatibility notes
Firefox 49 changed the parsing of 2-digit years to be aligned with the Google Chrome
browser instead of Internet Explorer. Now, 2-digit years that are less than
50 are parsed as 21st century years. For example,
04/16/17, previously parsed as April 16, 1917, will be April 16, 2017
now. To avoid any interoperability issues or ambiguous years, it is recommended to use
the ISO 8601 format like “2017-04-16” (bug 1265136).
Google Chrome will accept a numerical string as a valid
dateString parameter. This means that, for instance, while!! (“42”) evaluates to false in Firefox, it
evaluates to true in Google Chrome because “42” is
interpreted as the first of January 2042.

Convert String to Timestamp in Java | Delft Stack
HowToJava HowtosConvert String to Timestamp in JavaCreated: December-27, 2020Use lueOf() to Convert a String to Timestamp in JavaUse tTime() to Convert a String to Timestamp in JavaIn this article, we will introduce two methods to convert a string to a timestamp in Java. A timestamp is mainly used in databases to represent the exact time of some event. The Timestamp class we will use in this tutorial is a part of the lueOf() to Convert a String to Timestamp in JavaWe will use the TimeStamp class’s own static function – valueOf(). It takes a string as an argument and then converts it to a timestamp. One important thing to note here is to take care of the format in which the date and time are written in the string that we want to be converted into a timestamp. It is restricted to a fixed format, which is yyyy-mm-dd cannot change the format and then expect the right result, but instead, if we use an incorrect format, we will get an IllegalArgumentException in the output. In the below example, we have used 2020-12-12 01:24:23 as the date and time in the string, which follows the correct format of yyyy-mm-dd can now pass dateTime as the only argument of the valueOf(string) method, and it will convert a string to a;
public class StringToTimeStamp {
public static void main(String[] args) {
String dateTime = “2020-12-12 01:24:23”;
Timestamp timestamp = lueOf(dateTime);
(timestamp);}}
Output:2020-12-12 01:24:23. 0
We can get rid of the date and time formatting restrictions by using the same valueOf() method, but instead of directly passing a string to the method, we will use the LocalDateTime class. Because valueOf() accepts a LocalDateTime as an the following code, dateTime has a date and time which is then formatted using the DateTimeFormatter class’s ofPatter() method. We can use this formatter to parse and get a LocalDateTime object using the () we get a LocalDateTime object, we can pass it to lueOf(localDateTime) to convert the string to a;
import;
public static void main(String[] args) throws ParseException {
String dateTime = “01/10/2020 06:43:21”;
DateTimeFormatter formatDateTime = DateTimeFormatter. ofPattern(“dd/MM/yyyy HH:mm:ss”);
LocalDateTime localDateTime = ((dateTime));
Timestamp ts = lueOf(localDateTime);
(ts);}}
Output:2020-10-01 06:43:21. 0
Use tTime() to Convert a String to Timestamp in JavaThe second method to convert a string to a timestamp uses multiple classes and methods. Just like LocalDateTime, we can use our date and time format in the string. We used the SimpleDateFormate() class to format the string and then parse it to a Date need the Date object because it has the getTime() object, which returns the date and time as long. We can pass this long value to the constructor of Timestamp as we have done;
String inDate = “01/10/2020 06:43:21”;
DateFormat df = new SimpleDateFormat(“MM/dd/yyyy HH:mm:ss”);
Date date = (inDate);
long time = tTime();
Timestamp ts = new Timestamp(time);
Output:2020-01-10 06:43:21. 0
