Re: [tz] How to compute the moment of the next DST change

The tz file could be parsed itself as is being done in my free Windows product Time Zone Master, and a cron file produced from that. A new file would have to be generated after each release of the tz data files. On 2013-04-02 4:58, Simon Perreault wrote:

Dear time experts,

I want to write a cron job or similar that activates one week prior to daylight saving time changes. (Or, more generically, one week prior to any time jumps, for any reason, DST or else.)

Any pointers?

I have looked at the usual places: POSIX time functions, various date/time modules on CPAN, etc. Nothing seems to do that computation. Do I need to parse the tz database myself?

Thanks, Simon
