fat: create a function to calculate the timezone offest
Patch series "fat: timestamp updates", v5.
fat/msdos timestamps are stored on-disk with several different
granularities, some of them lower resolution than timespec64_trunc() can
provide. In addition, they are only truncated as they are written to
disk, so the timestamps in-memory for new or modified files/directories
may be different from the same timestamps after a remount, as the
now-truncated times are re-read from the on-disk format.
These patches allow finer granularity for the timestamps where possible
and add fat-specific ->update_time inode operation and fat_truncate_time
functions to truncate each timestamp correctly, giving consistent times
across remounts.
This patch (of 4):
Move the calculation of the number of seconds in the timezone offset to a
common function.
