John Shearer · Answer

currently checking that the original dates are used if I don t click those buttons

Anna Geller · Answer

the UI infers your time zone based on your UI settings that s why you see this date conversion Probably easier to switch to String

Anna Geller · Answer

I also asked the UI team will get back to you

John Shearer · Answer

I don t think this is a timezone issue but perhaps I misunderstand In this example `2021 10 10` becomes `2021 10 31`

John Shearer · Answer

GMT

John Shearer · Answer

thanks < Jenny>

Jenny · Answer

Thanks Let me look into that a bit further

Jenny · Answer

Hmm I m still not able to replicate that odd switch from 10 to 31 and I can t see any obvious reason for it in the code My guess is there s some oddity in time zone and the moment js library we re using I ll open a ticket

John Shearer · Answer

I just tried this on a helloworld flow from < Anna Geller> s ECS demo and have some more test cases as well as a perf issue just writing this up

John Shearer · Answer

For reference this is Google Chrome Version 96 0 4664 110 Official Build 64 bit on Win10 running on <http cloud perfect io|cloud perfect io>

John Shearer · Answer

The incorrect results only occur for some months 05 10 may oct inclusive independent from the year When calculating if the result will be incorrect it takes much longer 2 3 minutes for 12 dates Correct results come back instantaneously Please see attached for the testing I ve done Hope it helps

John Shearer · Answer

dropping the tz adjust doesn t make any difference afaict and the resulting json adds it back

Jenny · Answer

Thanks for the extra info < John Shearer>

Jenny · Answer

This is very strange and I still cannot replicate Can I ask you for a bit more info investigation Have you set your timezone from the user menu or is set at Local You can find the timezone selector by clicking on the avatar in the top right corner and then selecting Account Settings and Profile If you explicitly set your timezone to GMT in the user menu do you still see the odd conversions I m not convinced that the timezone is having an impact here since its from a date time string but I want to rule it out as it s the only thing that I can see that would explain you seeing this issue and me not being able to replicate it
