Local-dates: dates show days in the future

[supermathie (Michael Brown)]

For example:

[date=2019-06-05 timezone="America/Toronto" timezones="Africa/Cairo|America/Toronto|UTC"]

2019-06-05T04:00:00Z

shows up in preview and baked for me as:

UTC is not 52h in the future for me (it’s 4h ahead)

I know @zogstrip was hunting for a bug of this kind the other day, will assign him for now.

[zogstrip (Régis Hanol)]

Ok, I’m not crazy

Leaving a note for future me, here’s what I see now

The timezones are all wrong here… Paris, Paris, UTC

[supermathie (Michael Brown)]

@zogstrip

Paris, Paris

[zogstrip (Régis Hanol)]

Yeah, but it should show the ones in the timezones attribute… Not some apparently random ones

[supermathie (Michael Brown)]

you know me - love my images

Also, yes, Paris and Paris aren’t 24h apart…

[zogstrip (Régis Hanol)]

Pretty sure I fixed that in

We were mutating the same dateTime object when generating the previews (ie. the date ranges in the tooltip), thus creating a discrepancy in the space time continuum .
