This is the command I am using:
last -x|grep shutdown | head -1
but it's giving me the duration with +2 hours:
shutdown system down 3.14-1-amd64 Mon Jul 21 08:43 - 22:19 (13:36)
the last shutdown time (08:43) is correct, but the startup time (22:19, should be 20:19) is incorrect.
Is there a better command to check how long ago the PC was shutdown? or is my DST settings or something else causing this?
PS: I am using Debian testing (Linux rig 3.14-1-amd64 #1 SMP Debian 3.14.12-1 (2014-07-11) x86_64 GNU/Linux)
