The checkbox does not automatically adjust for daylight savings time.
Next click the date time tab to set the date.
It is the number of seconds that have elapsed since the unix epoch minus leap seconds.
For example if you start a process at 01 59 00 on the day in which daylight savings summer time takes effect in a locale in which the time change is at 02 00 and the process takes two minutes then the real elapsed time will be two minutes while the wall clock will show a difference of one hour and two minutes.
Due to this treatment unix time is not a true representation of utc.
The gettimeofday system call gets the system s wall clock time.
