I’ve just moved my cluster over to a DO Droplet and this is working correctly on there. As far as I can see, all the timezone stuff is set the same as the Pi I was using and I just cloned my spider folder over.

As you can see, if the locale is local (use_localtime is true) then the values in the hour (in particular) is compared with the outcome of using localtime(), rather than gmtime(). At the moment of comparison, the code does not know (nor care) what timezone it is in. It just compares two values. So I remain confused.

NOTE: 'set/debug cron' must have been set *before* any fault in order for grepdbg to pick it up. Then send me a representative sample of data that you collect (directly rather than via the list).
