10:36 <olbat> Hey guys, sorry to bother you again (hopefully this will by the last MR of my MR streak), I need someone from the core team to review/merge this one: https://github.com/crystal-lang/crystal_lib/pull/74 . Thank in advance :)

13:32 <FromGitter> <asterite> Merged!

13:34 <olbat> Thanks! <3

13:46 <astronavt> hello crystal people - i was discussing date/time library stuff with someone, and they pointed out that crystal will let you instantiate "ambiguous" Time objects that could correspond to 2 different unix timestamps, such as `Time.local(2021, 11, 7, 1, 30, 0, location: Time::Location.load("America/New_York"))` which could correspond to 01:30 *before* the DST transition on that day, or *after*

13:47 <astronavt> in this case it looks like it chooses the former (-4:00), but is there some way to handle this ambiguity? or is the answer to use explicit offsets if that level of precision is required, instead of going by the tz location name?

13:47 <astronavt> (at least, that is supposed to be the DST transition date according to this random website which might or might not be correct https://www.timeanddate.com/time/change/usa?year=2021)

15:35 <FromGitter> <Blacksmoke16> any reason to not just use `UTC` or unix timestamps if you need that precision?

16:06 <straight-shoota> astronavt, Time instances themselves are always unambiguos. The only thing that is ambiguous is the transformation from a calendrical representation.

16:07 <straight-shoota> So to disambiguate that transformation process, you need to use unambiguous time zon information. A location that observes daylight savings time is inheretly ambiguous at a backwards shift.

16:09 <straight-shoota> If you have an ambiguous calendrical representation `2021-11-07 01:30:00`, you'll have to provide a precise time zone offset (like -4:00 offset)

16:13 <straight-shoota> After initializing the instance, you can then apply the desired named time zone in order to not keep a static offset but follow the specific time zone rules

19:37 <FromGitter> <Blacksmoke16> is dark theme on the forums broken for anyone else?

19:50 <jhass> yeah, couple of days already

20:38 <FromGitter> <Blacksmoke16> Super annoying
