A value of "2023-03-12T02:00:00.000" breaks the Date Time component. I'm assuming this is due to Daylight Saving Time, even though I have the "Manage time zone" setting off. It fails with it on even if the "Display" and "Value" zones are both set to UTC.
It's like Retool thinks that UTC hour is existentially impossible.
We have a system which lists tasks critical to our business in order of when they're due by. By happenstance (and default sorting in a table) our queue showed a sequence of null-date-time values right at the top, which alerted me to the fact that something was wrong.
Had I not seen this the implications for our customers could've been significant.
Aaaand this bug has been fixed! It should go live with our next Cloud Deploy (which happens every few week days). Thank you @dguzzo for surfacing this issue and thank you Jay for the workaround in the meantime
