Feature #8508
openUse C++20's time zone support in std::chrono by default if supported.
0%
Description
C++ compiler and STL implementations are getting C++20 feature complete, so we can look into replacing the date library with it. This would be especially nice on Windows, since using time zones on Windows would not require extra setup anymore.
This was done in issue #8595 similarly to how we do Wt::cpp17::any:
- Have a CMake option to select the implementation, defaulting to the STL implementation if supported
- Introduce a
Wt::cpp20::chrononamespace that is aliased tostd::chronoordate
WDate, WTime, WDateTime, and WLocalDateTime may no longer be necessary. We could look into adding overrides in the right places, so that their use can be avoided if desired.

Updated the description to more accurately reflect the fact that we already implemented those two bullet points in issue #8595.

What remains now is to automatically determine whether we can use std::chrono for time zones, and enable it by default if available, still allowing the user to specify which one they want to use.
What also remains is the ability to take a std::chrono::year_month_day instead of a WDate in places like WDateEdit, so we don't need to necessarily use WDate anymore, and similar things for WTime, WDateTime, and WLocalDateTime.
