I have been using tune2fs to determine the age of my Linux distribution installations but without knowing the time zone the date in it is less useful. The exact command I am using is from here, here it is just for the sake of clarity:
sudo tune2fs -l /dev/sda3 | grep created | sed 's/.*created\:\s*//g'
but the output is of the form:
Fri Jun 23 23:59:22 2017
Note how there is no time zone mentioned. But
date returns output of the form:
Sun Jul 23 17:58:18 AEST 2017
Notice how the time zone AEST is mentioned. I have read the man page of
tune2fs. I have searched for "date", "created", "time" in it using my Web browser's find utility and I haven't found a single mention of the time zone of the date format, or if there is a way to manually set it. I have run DuckDuckGo searches for "tune2fs date" and "tune2fs timezone" and I looked at the top five results and couldn't find anything relevant in them.
