Linux / UNIX: Convert Epoch Seconds To the Current Time
how you can obtain the UNIX epoch time (number of seconds since 1970-01-01
00:00:00 UTC) using the Linux bash "date" command. It also shows how you can
convert a UNIX epoch time to a human readable time.
Obtain UNIX epoch time using bash
Obtaining the UNIX epoch time using bash is easy. Use the build-in date command and
instruct it to output the number of seconds since 1970-01-01 00:00:00 UTC. You can do this
by passing a format string as parameter to the date command. The format string for UNIX
epoch time is '%s'.
Print Current UNIX Time
Type the following command to display the seconds since the epoch:
Syntax: date +%s
date +%s
1569569962
Convert Epoch To Current Time
Type the command:
date -d @Epoch
date -d @1569569962
date -d "1970-01-01 1569569962 sec GMT"
Sample outputs:
Fri Sep 27 13:09:22 IST 2019
To convert number of seconds back to a more readable form, use a command like this:
date -d @1569569962 +"%d-%m-%Y %T %z"
Using AWK
awk 'BEGIN { print strftime("%Y-%m-%d %H:%M:%S", 1569569962); }'
Output:
2019-09-27 13:09:22
Using Perl
perl -e 'print scalar(localtime(1569569962)), "\n"'
Output:
Fri Sep 27 13:09:22 2019
