||The never ending saga of not announcing the times of marathon matches correctly continues. Here is an example from the most recent announcement I received via email:
The final full length Marathon Match of the 2017 Topcoder Open Marathon is a week away. The match will begin at 21:00 UTC -4 on Wednesday, July 5 and goes through July 19 at 21:00 UTC -4.
In Gmail, hovering over the date will bring up an "add to calendar" popup, but this will add something in time zone UTC not UTC-4. I think this problem is caused by the space before the minus sign.
