How to get the present Unix timestamp in different programming languages?
Java time
JavaScript Math.round(new Date().getTime()/1000)
getTime() The return value is in milliseconds
Microsoft .NET / C# epoch = (DateTime.Now.ToUniversalTime().Ticks - 621355968000000000) / 10000000
MySQL SELECT unix_timestamp(now())
Perl time
PHP time()
PostgreSQL SELECT extract(epoch FROM now())
Python First import time then time.time()
Ruby Get Unix timestamp: Time.now or Time.new
Print Unix timestamp: Time.now.to_i
Go First import time then int32(time.Now().Unix())
SQL Server SELECT DATEDIFF(s, '1970-01-01 00:00:00', GETUTCDATE())
Unix / Linux date +%s
VBScript / ASP DateDiff("s", "01/01/1970 00:00:00", Now())
Other operating systems
(If Perl installed)
Command line: perl -e "print time"
How to Convert Unix Timestamp to Common Time in Different Programming Languages?
Java String date = new java.text.SimpleDateFormat("dd/MM/yyyy HH:mm:ss").format(new java.util.Date(Unix timestamp * 1000))
JavaScript First var unixTimestamp = new Date(Unix timestamp * 1000) Then commonTime = unixTimestamp.toLocaleString()
Linux date -d @Unix timestamp
MySQL from_unixtime(Unix timestamp)
Perl First my $time = Unix timestamp Then my ($sec, $min, $hour, $day, $month, $year) = (localtime($time))[0,1,2,3,4,5,6]
PHP date('r', Unix timestamp)
PostgreSQL SELECT TIMESTAMP WITH TIME ZONE 'epoch' + Unix timestamp) * INTERVAL '1 second';
Python First import time Then time.gmtime(Unix timestamp)
Ruby Time.at(Unix timestamp)
SQL Server DATEADD(s, Unix timestamp, '1970-01-01 00:00:00')
VBScript / ASP DateAdd("s", Unix timestamp, "01/01/1970 00:00:00")
Other Operating Systems
(If Perl is installed on the system)
Command Line: perl -e "print scalar(localtime(Unix timestamp))"
How to Convert Common Time to Unix Timestamp in Different Programming Languages?
Java long epoch = new java.text.SimpleDateFormat("dd/MM/yyyy HH:mm:ss").parse("01/01/1970 01:00:00");
JavaScript var commonTime = new Date(Date.UTC(year, month - 1, day, hour, minute, second))
MySQL SELECT unix_timestamp(time)
Time Format: YYYY-MM-DD HH:MM:SS or YYMMDD or YYYYMMDD
Perl First use Time::Local Then my $time = timelocal($sec, $min, $hour, $day, $month, $year);
PHP mktime(hour, minute, second, month, day, year)
PostgreSQL SELECT extract(epoch FROM date('YYYY-MM-DD HH:MM:SS'));
Python First import time Then int(time.mktime(time.strptime('YYYY-MM-DD HH:MM:SS', '%Y-%m-%d %H:%M:%S')))
Ruby Time.local(year, month, day, hour, minute, second)
SQL Server SELECT DATEDIFF(s, '1970-01-01 00:00:00', time)
Unix / Linux date +%s -d"Jan 1, 1970 00:00:01"
VBScript / ASP DateDiff("s", "01/01/1970 00:00:00", time)
Introduction to Tools

What is Unix timestamp: Unix timestamp, or Unix time, POSIX time, is a time representation defined as the total number of seconds from 00:00:00 GMT on January 01, 1970 to the present. Unix timestamps are used not only in Unix systems, Unix-like systems, but also in many other operating systems.
