at present i have this:
for file in `find ${my_dir}/ -name "*_statsfile_??????????????.gz" -print`
do
ONEDAY=86400
NOW=$(date -u +%Y%m%d%H%M%S)
FILEDATE=`echo $file | sed -e 's/^.*_stats_//g' -e 's/\.gz$//g'`
((DIFF=$NOW - $FILEDATE))
CALC_DIFF=$(($DIFF / $ONEDAY))
echo "[$file], Current Time: $NOW. File Time: $FILEDATE. Difference: $CALC_DIFF."
done
both dates need to be in UTC. Is there a way to make them BOTH UTC. the date 'NOW' is UTC but the 'FILEDATE' isnt.

battery-stats
BATTERY-STATS(5) File Formats Manual BATTERY-STATS(5)
NAME
battery-stats - collected battery statistics
DESCRIPTION
The battery-stats contains statistics about battery charge over time, as collected by the battery-stats-collector (8) daemon.
FORMAT
Each line in the file represents one sample and is of the form:
<seconds> <charge%> <powermode> <UTC-date> <UTC-time>
separated by spaces and terminated by a newline.
Where:
seconds
is the number of seconds since 1st Jan 1970 00:00:00 UTC
charge%
is the battery charge a number between 0 and 100
powermode
indicates the power mode:
0 A/C off
1 On battery
2 On backup power
UTC-date
a human-readable date in the format YYYY/MM/DD. Note that this is in UTC, not the local or system timezone.
UTC-time
a human-readable time in the format HH:MM:SS (using a 24-hour clock). Note that this is in UTC, not the local or system timezone.
minutes-left
is the BIOS estimate of how many minutes of running time the battery would provide. This may be unreliable, depending on the BIOS
through which it was collected.
EXAMPLE
A battery under charge might result in the following samples:
1032651245 27 1 2002/09/21 23:34:05 94
1032651275 28 1 2002/09/21 23:34:35 97
1032651305 29 1 2002/09/21 23:35:05 100
1032651335 30 1 2002/09/21 23:35:35 103
1032651365 30 1 2002/09/21 23:36:05 106
FILES
The default set-up is to save battery statistics in /var/log and rotate the logs weekly, which results in this set of files:
/var/log/battery-stats - current (most recent) statistics
/var/log/battery-stats.[0-9]+ - less recent statistics
/var/log/battery-stats.[0-9]+.gz - ancient statistics
