What is your $TZ value ?
If you set TZ to GMT+5 or something, the clock will always be 5 hours west
of Greenwich without any DST rules.
Try zdump -v $TZ
The clock never change, and the displayed time is personal, depending on your TZ, but if you don't have any, it's the system default TZ.
This is to make it possible to use as a multiuser system, not as windows toys
where it's impossible to check how old a file is.
e.g , you can see the date, but if you don't know in which timezone it was created/modified, you don't know what offset to apply.
Any timestamp in unix/linux will be translated to your TZ.
If you dual boot with windows, you have one system that change the clock,
and one system that change the offset from a clock that must never be changed.
In this case, windows mess up your hardware, and only ntp can save you.
