faf70cc9941ce2b0ce4fd48ecfdbe28194adb8ba Remove wallet::ParseISO8601DateTime, use ParseISO8601DateTime instead (MarcoFalke)
2222aecd5f8059785e655da7b7e3fcc59204245c util: Implement ParseISO8601DateTime based on C++20 (MarcoFalke)
Pull request description:
`boost::posix_time` in `ParseISO8601DateTime` has many issues:
* It parses random strings that are clearly invalid and returns a time value for them, see [1] below.
* None of the separators `-`, or `:`, or `T`, or `Z` are validated.
* It may crash when running under a hardened C++ library, see https://github.com/bitcoin/bitcoin/issues/28917.
* It has been unmaintained for years, so reporting or fixing any issues will most likely be useless.
* It pulls in a third-party dependency, when the functionality is already included in vanilla C++20.
Fix all issues by replacing it with a simple helper function written in C++20.
Fixes https://github.com/bitcoin/bitcoin/issues/28917.
