I thought it was just a typo. I actually read it about 3 or 4 times before I saw it. I thought it was amusing. ( I'm good at it myself. )
If the maintenance will start at 1 PM Eastern Daylight Time today (Oct. 16th) in the US, then that will be 8 PM Eastern Summer Time in Australia on Oct. 15th. (Summer Time started a few weeks ago and is GMT +11 in QLD.)
Time math is one of the more difficult concepts, in my opinion.
No daylight savings time in Queensland, just the southern states.
Time math can get confusing. Australia is ahead of the USA, you put us behind. (The maintenance shut should of happened here on Saturday the 17th, 3 am)
Enjoy your day.
