Formatting timestamps in the kernel

My driver creates an entry in /proc that displays time related events. Is there a way to format timestamps, as absolute date & time, honoring timezones etc., within the kernel? I think I read somewhere that timezones are considered a userspace concept, and as such are not supported within the kernel. Thanks, Neil

Correct. Your best bet is probably to use "seconds and fractions since boot", since you can steal all the code you need from printk(). Next best is to use epoch seconds and fractions.
