Can someone double-check if the meeting time is correct? I believe we're entering the daylight savings time mess, aren't we?

Oops, my calendar shows the meeting in 5 minutes, which is 7pm UTC.

It seems everyone has come around to @t-bast's meeting time change, I'm gonna go get lunch, be back in an hour.

[t-bast]

I think I'll change the future meeting headers to say 5:30am Adelaide time if that's the official time, it's less error-prone (or it lets everyone make the mistake by having everyone do the time conversion themselves 😄)

@LightningHelper we skipped that meeting, so nothing to look for in the logs.
