(Note that > this might conflict with the idea of your local DOS, but applying the msdosfs use adjkerntz kernel variable to calculate local timezone for DOS files, check msdosfs sources. adjkerntz kernel variable maintained by adjkerntz uility. I plan to run adjkerntz utility in any case, i.e. for UTC clock too without touching RTC or kernel time but maintain adjkerntz kernel variable only for msdosfs and similar filesystems with local timezone. > localtime does as well conflict with the idea of any other DOS not > running in *your* localtime zone.) Proper DOS/Windows software sends timezone offset of your DOS with any file times. > To be honest, even in cases where i run DOS every now and then, i > simply don't care for its broken idea of a timezone.
