[SOLVED] Which time does the `crontab` listen to? Local, Universal or RTC time?

Issue

Following is the result of the command, timedatectl, which lists different "types" of time.

• Local time
• Universal time
• RTC time

Which time do the crontab listen to as my cron-job is not running.

$ timedatectl
                      Local time: Thu 2019-12-26 15:43:38 IST
                  Universal time: Thu 2019-12-26 10:13:38 UTC
                        RTC time: Thu 2019-12-26 10:13:39
                       Time zone: Asia/Kolkata (IST, +0530)
       System clock synchronized: yes
systemd-timesyncd.service active: yes
                 RTC in local TZ: no

Solution

As quoted in crontab manual

"The time used for writing into a log file is taken from the local time zone, where the daemon is running."

So your cronjob will be running according to your local timezone i.e. Local time.
