I would learn a thing or two.

What range would be reasonable? I prefer midnight to 6am, for example. At least for now, Yilun (China) and myself (Australia) are ok with these times.

Let's use a tool: https://crab.fit/iommufd-tsm-call-593432
Please vote.

And later on, Australia goes into DST, the nothern hemisphere - off DST (but not the same weekend, of course), and we'll start this all over again, may be.

We'll still have the tomorrow call at the old time. Thanks,
