What is epoch time?

The Unix epoch (or Unix time or POSIX time or Unix timestamp) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (in ISO 8601: 1970-01-01T00:00:00Z). Literally speaking the epoch is Unix time 0 (midnight 1/1/1970), but 'epoch' is often used as a synonym for 'Unix time'. Many Unix systems store epoch dates as a signed 32-bit integer, which might cause problems on January 19, 2038 (known as the Year 2038 problem or Y2038).
The converter on this page converts timestamps in seconds, milliseconds and microseconds to readable dates.

Human readable time  Seconds
1 hour 3600 seconds
1 day 86400 seconds
1 week 604800 seconds
1 month (30.44 days)  2629743 seconds
1 year (365.24 days)   31556926 seconds
 

How to get the current epoch time in ...

Python import time; time.time()
Ruby Time.now (or Time.new). To display the epoch: Time.now.to_i
Perl time more ...
Java long epoch = System.currentTimeMillis()/1000;
C# var epoch = (DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc)).TotalSeconds;

Convert from human readable date to epoch

PHP strtotime("15 November 2018") (converts most English date texts) or:
date_create('01/15/2018')->format('U') (PHP5 DateTime class) more ...
Python import time; int(time.mktime(time.strptime('2000-01-01 12:34:00', '%Y-%m-%d %H:%M:%S'))) - time.timezone
Ruby Time.local(year, month, day, hour, minute, second, usec ) (or Time.gm for GMT/UTC input). To display add .to_i
Perl Use the Perl Epoch routines
Java long epoch = new java.text.SimpleDateFormat("MM/dd/yyyy HH:mm:ss").parse("01/01/1970 01:00:00").getTime() / 1000;
VBScript/ASP DateDiff("s", "01/01/1970 00:00:00", time field) more ...
AutoIT _DateDiff('s', "1970/01/01 00:00:00", "YYYY/MM/DD HH:MM:SS")
Delphi Epoch := DateTimeToUnix(StrToDateTime(myString));
C Use the C Epoch Converter routines
R as.numeric(as.POSIXct("YYYY-MM-dd HH:mm:ss", tz = "GMT", origin="1970-01-01")) The origin parameter is optional
Go Example code
Adobe ColdFusion int(parseDateTime(datetime).getTime()/1000);
MySQL SELECT unix_timestamp(time) Time format: YYYY-MM-DD HH:MM:SS or YYMMDD or YYYYMMDD
More on using Epoch timestamps with MySQL
PostgreSQL SELECT extract(epoch FROM date('2000-01-01 12:34'));
With timestamp: SELECT EXTRACT(EPOCH FROM TIMESTAMP WITH TIME ZONE '2018-02-16 20:38:40-08');
With interval: SELECT EXTRACT(EPOCH FROM INTERVAL '5 days 3 hours');
SQLite SELECT strftime('%s',timestring);
SQL Server SELECT DATEDIFF(s, '1970-01-01 00:00:00', time field)
JavaScript Use the JavaScript Date object
Unix/Linux Shell date +%s -d"Jan 1, 1980 00:00:01" Replace '-d' with '-ud' to input in GMT/UTC time.

Convert from epoch to human readable date

PHP date(output format, epoch); Output format example: 'r' = RFC 2822 date more ...
Python import time; time.strftime("%a, %d %b %Y %H:%M:%S +0000", time.localtime(epoch)) Replace time.localtime with time.gmtime for GMT time. Or using datetime: import datetime; datetime.datetime.utcfromtimestamp(epoch).replace(tzinfo=datetime.timezone.utc)
Ruby Time.at(epoch)
C# private string epoch2string(int epoch) {
return new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc).AddSeconds(epoch).ToShortDateString(); }
Perl Use the Perl Epoch routines
Java String date = new java.text.SimpleDateFormat("MM/dd/yyyy HH:mm:ss").format(new java.util.Date (epoch*1000));

AutoIT _DateAdd("s", $EpochSeconds , "1970/01/01 00:00:00")
Delphi myString := DateTimeToStr(UnixToDateTime(Epoch)); Where Epoch is a signed integer.

Go Example code
Adobe ColdFusion DateAdd("s",epoch,"1/1/1970");
MySQL FROM_UNIXTIME(epoch, optional output format) Default output format is YYY-MM-DD HH:MM:SS. If you need support for negative timestamps: DATE_FORMAT(DATE_ADD(FROM_UNIXTIME(0), interval -315619200 second),"%Y-%m-%d") (replace -315619200 with epoch) more ...
PostgreSQL PostgreSQL version 8.1 and higher: SELECT to_timestamp(epoch); Older versions: SELECT TIMESTAMP WITH TIME ZONE 'epoch' + epoch * INTERVAL '1 second';
SQLite SELECT datetime(epoch_to_convert, 'unixepoch'); or local timezone: SELECT datetime(epoch_to_convert, 'unixepoch', 'localtime');
Oracle PL/SQL SELECT to_date('01-JAN-1970','dd-mon-yyyy')+(1526357743/60/60/24) from dual

Microsoft Excel / LibreOffice Calc =(A1 / 86400) + 25569 Format the result cell for date/time, the result will be in GMT time (A1 is the cell with the epoch number). For other time zones: =((A1 +/- time zone adjustment) / 86400) + 25569.
Crystal Reports DateAdd("s", {EpochTimeStampField}-14400, #1/1/1970 00:00:00#) -14400 used for Eastern Standard Time. See Time Zones.

IBM PureData System for Analytics select 996673954::int4::abstime::timestamp;
Unix/Linux Shell date -d @1520000000 Replace 1520000000 with your epoch, needs recent version of 'date'. Replace '-d' with '-ud' for GMT/UTC time.
Mac OS X date -j -r 1520000000
PowerShell Function get-epochDate ($epochDate) { [timezone]::CurrentTimeZone.ToLocalTime(([datetime]'1/1/1970').AddSeconds($epochDate)) }, then use: get-epochDate 1520000000. Works for Windows PowerShell v1 and v2
Other OS's Command line: perl -e "print scalar(localtime(epoch))" (If Perl is installed) Replace 'localtime' with 'gmtime' for GMT/UTC time.
