When I run gsettings get com.ubuntu.update-manager launch-time the response is 1382579402. What does the value of 1382579402 mean?

That's presumably a time in Unix epoch format, i.e. seconds since 01/01/1970 UTC. It tells you when update manager last ran (see e.g. here).

You can display it in a more user-friendly way with the date utility.

 $ date --date="@1382579402"
Thu Oct 24 03:50:02 CEST 2013

Or perl:

 $ perl -e 'print localtime(1382579402)."\n";'
Thu Oct 24 03:50:02 2013

To get the current time in that format:

 $ date +%s      # note: lowercase "s"

So in this context, it is the date and time I first ran update manager? – DK Bose Mar 2 '14 at 11:53
No, last time it ran (see e.g. here). – Mat Mar 2 '14 at 11:54
Perfect. Maybe you can add that to the answer :) I'll accept it as soon as I'm able to. – DK Bose Mar 2 '14 at 11:56
