Would you consider adding timezone management to DateTimeField?

[Colin-b]

We store our values as UTC localized but we expect our clients to use another timezone that make more sense when using the interface.

Having the ability to specify a data timezone and a display timezone would be nice, but maybe this is too far fetched.

What do you think?

If you are open to the idea, I could draft a PR for this.

Thanks again

With datetime.utcnow() being deprecated and replaced by datetime.now(UTC), it becomes impossible to compare the latter with offset-naive datetimes provided through wtforms. If not addressed, this issue will likely make wtform not compatible with future python version
