RAC Winter Contest start time
« on: December 25, 2019, 08:17:14 AM »

I sometimes get confused with GMT and UTC. The RAC contest starts at 0000 UTC on Dec 28. Is that 0000 Friday or Saturday in North America?

There are 5 time zones on the NA continent and the USA encompasses 11 time zones in total, so you need to be more specific.

A Google query such as "00:00 UTC to CST" would return return 6:00 PM (18:00) the day before. CST is the central time zone in the US. The population centers of the US are in EST (Eastern) and PST (Pacific/Western).

Watch out for daylight savings time changes in summer. And just to keep things complicated, some areas in the US don't observe daylight savings time.

I hope that helps.

Sorry for being vague. I’m in the pst time zone (CA). I know that sometimes contests start a day earlier, like on Friday because GMT is a day ahead, but the RAC contest is Canadian sponsored so I was just wondering if it was a 0000z start time on Fri or Sat. Good explanation on the time zones. Thank you.

The RAC webpage states:

Note: the RAC Canada Winter Contest 2019 will be held on December 28, 2019.

Since they are using UTC for the start time designation, this would mean that the contest starts at 4 PM PST on the 27th of December - if they are being consistent. But organizations frequently get this wrong so you may wish to check with them to be certain.

The RAC Winter contest runs from 0000 - 2359 UTC on December 28th, so it starts at 1900 EST for us on the Right Coast of the US on 27 December, or 1600 PST for those on the Wrong Coast...
