in reply to Windows / Linux puzzler

I hope I can contribute something, although I definitely don't know exactly whats going on.

First suspicion: the time() function is not the same on both platforms.

Second suspicion: the settings file for $squelch doesn't have exactly what you think.

Last suggestion: work around by subtracting 1 from squelch or adding 1 to $min, or the other way round.

Probably not exactly what you're looking for but I hope it may help.

Cheers, JAWPH

    I like your first suspicion more than your second. I'm pretty sure what's in that file. I will investigate. The notion of a workaround has also occurred to me. Thanks,

      Sorry, but personally I find the AM's first suggestion less likely, time should be portable across platforms, and it being off by an entire minute would be an obvious problem. I do think you should investigate the values of your variables on both platforms though: output them via Data::Dumper with $Data::Dumper::Useqq=1; or Data::Dump (see also the Basic debugging checklist).

        It does not have to be off by an entire minute to cause this type of problem. A few milliseconds would be enough if the code we see is only run once per minute to check if any emails should be sent. If I understand correctly, between greater timing accuracy and a more efficient scheduler, the code could be seeing "10.03" minutes in Windows and "9.97" minutes (then "10.96" when the email is sent "11 minutes later") in Linux.

        Rather than dumping everything, I modded the code to print out the quantities being compared. More testing required. I'll get back to you. Thanks,

        I was able to rule out time as the joker in the deck, if only because we're dealing with an interval of time, not the time of some event. Thus it shouldn't matter if time() returns different values on the two systems.
