One way is to change the TZ variable in the script. example you are in MST (+7), pick a timezone two hours earlier like EST
Code:
export TZ=MST7MDT
date
export TZ=EST5EDT
date

the 7 and the 5 are important you can make up 3 letter names for the timezone, or just reuse the current timezone. You can fudge time by as much as +12 -12 hours.

Otherwise see the datecalc script in Perderabo's thread 'Date Arithmetic' in the forums FAQ.

#include <pcp/pmapi.h> int pmWhichZone(char **tz); cc ... -lpcp DESCRIPTION

SEE ALSO
