DateTime returns off-by-one date

[mahdafr]

Describe the bug

When I use the gr.DateTime as an input field, and select a date, the field fills with the previous date (off-by-one). It also reports to the callback function the off-by-one date. Video shows example of bug.

Hi madam @mahdafr, I'm interested to solve this issue... Could you please tell the location of the code ?

[mahdafr]

I'm not sure what you mean - the Reproduction has all the code I have used to run into the bug. Is that what you meant?

[mahdafr]

Woah, that's an interesting bug! Can't wait for the release 🥳

Thanks!
