That's all very fine if you know what the difference is between PST and UTC and/or your local time and whether you're on DST or not and if I'm on DST - so how many sums do I have to do? Have a look and see where I live - do you know what time it is here off the top of your head - no, of course not. Sure, it's not rocket science but it would be a damn sight easier if you put 0500(PST) 1200(UTC) or whatever it is.
This is a good example as to why they put the Universal in to UTC so that everybody can know what time it is. The time of my post is 20:22 UTC. The time of my post is in local time (UTC -7) is 13:22. Now, everyone can know what time I posted with no confusion.
Well done, scannerboy01. I know quite a few that do post in UTC and I believe in the intro for newbies it says that times should be expressed in UTC. I have a digital clock in my radio stack that shows UTC and when I record anything in the middle of the night I use a stereo recorder programme (RipVynil or ScanRec) and have WWV on one track for later listening - fortunately they don't use PST or whatever
