Yep - I understood that, Tim. Thew issue seems to be that cron pays no attention to TZ declarations that happen AFTER it wakes up - cron does not parse the job times using the new TZ. The thing I am struggling with is that 'date' picks up the changes imposed by 'TZ=', but then 'cron' parses the next line as if the job times are interpreted using the server's default TZ. I've tried using 'CRON_TZ=' as well as, and instead of, 'TZ=' - to no avail. What I thought ought to happen is this: * 'cron' wakes up; * 'cron' works through the crontab line by line; * at line 1 cron changes the TZ to America/NY; * at line 2 cron reads the job time in the context of having just been told that it's operating in the NY timezone (thus 45 13 * * * is 1:45 pm NY time); . . . * at line 15 cron is told to change the TZ to Australia/Sydney; * from line 14 onwards, 45 13 * * * is 1:45 pm SYDNEY time. . . . and so on. It seems that cron behaves as if it forgets $TZ at each newline within a given cron instance. The silly thing is, with all the time I've wasted pursuing this wild goose I could have built the required four crontabs, and written the script to swap them in and out on the appropriate dates. (Or I could have spent $100 and bought a shared-hosted server space to do the Australian-TZ stuff and given it sufficent permission to store the resultant data in y primary mySQL db...) Still, I think it's worth persevering with. I'm certain it can be done. > You might want to try some other determining factor, such as a shell > builtin. > > > Good luck.
