Re: print current date and time in a kernel module

["Manoj Gupta" <manoj334@xxxxxxxxx>]

In my understading, "xtime" variable stores the current time and date, which has 

tv_sec - seconds elapsed since January 1, 1970 (UTC)
tv_nsec - nanoseconds in the last second

You don't. The kernel doesn't have an idea about current date and time.
Date and time depends on timezone rules, and that's userspace. If you
need date and time of your local timezone in your kernel module, your
module is broken by design.
