Additional arithmetics, formatting and parsing functions for std.Datetime.

[asterkin]

Use Case

1. There is a need to perform simple plus/minus arithmetics between std.DateTime and Duration: let now = datetime.systemNow(); let expiration = now + duration.fromHours(1); let validFor = expiration - now; assert(now <= expiration); assert(expiration > now); ...
2. There is a need for additional formatting and parsing functions: let now = datetime.utcNow(); log(now.toUtcString()); let sd = "2024/06/18 16:15"; let d = datetime.parse(sd, datetime.YYYYMM_HHMM); assert(d.format(datetime.YYYYMM_HHMM), sd);

Proposed Solution

You may find a sample implementation here: https://github.com/asterkin/endor.w/tree/main/datetimex

Implementation Notes

Some conversions from JavaScript Date to Wing DateTime are performed via ISO string which is inefficient.

I ran into friction with this as well -- it would be great to have more operations adding, subtracting, and comparing dates and durations where appropriate. See also these issues (https://github.com/winglang/wing/issues/6297) and (https://github.com/winglang/wing/issues/6298).

An example would be "I would like to obtain a datetime value representing one week from now".

Formatters for converting datetime to strings would also be helpful
