That's interesting, but sadly that move makes the problem worse rather than better, although that view is (of course) subjective.
If I read that update right, then moving forward PGC will now be reporting the 'found date' for Lab Caches to match the date produced by Groundspeak. Whilst I can sort of applaud a certain uniformity of data, Groundspeak currently record Lab Cache finds in accordance with Seattle time (PST I think) instead of local time.
That won't make much of a difference to cachers in the USA but is an almighty pain in the arse for anyone else, the problem getting bigger the further away you are.
For us poor buggers in New Zealand, who are currently 21hrs ahead of PST, that means currently the ONLY way to get a Lab Cache find to actually be factually correct is to only find them between 9pm and midnight!
