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. Some 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 (10-digit), milliseconds (13-digit) and microseconds (16-digit) to readable dates.

PHPtime() More PHP
Pythonimport time; time.time() Source
RubyTime.now (or Time.new). To display the epoch: Time.now.to_i
Perltime More Perl
Javalong epoch = System.currentTimeMillis()/1000; Returns epoch in seconds.
C#DateTimeOffset.Now.ToUnixTimeSeconds() (.NET Framework 4.6+/.NET Core), older versions: var epoch = (DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc)).TotalSeconds;
Objective-C[[NSDate date] timeIntervalSince1970]; (returns double) or NSString *currentTimestamp = [NSString stringWithFormat:@"%f", [[NSDate date] timeIntervalSince1970]];

PostgreSQLPostgreSQL version 8.1 and higher: SELECT to_timestamp(epoch); Source Older versions: SELECT TIMESTAMP WITH TIME ZONE 'epoch' + epoch * INTERVAL '1 second';

PowerShellFunction get-epochDate ($epochDate) { [timezone]::CurrentTimeZone.ToLocalTime(([datetime]'1/1/1970').AddSeconds($epochDate)) }, then use: get-epochDate 1520000000. Works for Windows PowerShell v1 and v2
