# Run fix-fat-dst-modtimes.py on Android to adjust file
# modification times on your FAT32 $data copy up or down 
# by an hour, to make them in synch with non-FAT32 drive 
# times after a daylight-savings-time (DST) rollover.
# Example: "bash <thisfile>.sh -add 1 <logfilename>?".
# This uses path variables set in your ~/.bash_profile.
# See _README.html for all general usage instructions.
