Refactor Local #1072

pitdicker · 2023-05-18T15:51:40Z

This extracts two commits from #1017.

The platform-specific implementations of Local can get quite a bit simpler if they just return the offset for a local or UTC NaiveDateTime, instead of constructing a DateTime themselves. This also allows them to pick up the fix in #1071.

The second commit was for a strange difference: Utc::now uses the standard library to get the current date, while for Local::now we call a Windows API ourselves. Because on both Unix and Windows we (should) get an UTC timestamp from the OS and then convert it to local time, we may just as well always use Utc::now inside Local::now and be consistent.

I think I'd prefer to keep the non-WASM and wasmbind code in the same module. Or maybe both stub and wasmbind can become inline modules? In either case, please think about the optimally reviewable commit sequence for making changes like this.

Inline modules are a good idea 👍.

In either case, please think about the optimally reviewable commit sequence for making changes like this.

I made an effort.

Looks good, thanks!

One builder seemed stuck. I have rebased on the current 0.4.x for another run.

This PR contains the following updates: | Package | Type | Update | Change | |---|---|---|---| | [chrono](https://github.com/chronotope/chrono) | dependencies | patch | `0.4.24` -> `0.4.26` | --- ### Release Notes <details> <summary>chronotope/chrono</summary> ### [`v0.4.26`](https://github.com/chronotope/chrono/releases/tag/v0.4.26): 0.4.26 [Compare Source](chronotope/chrono@v0.4.25...v0.4.26) The changes from [#807](chronotope/chrono#807) we merged for 0.4.25 unfortunately restricted parsing in a way that was incompatible with earlier 0.4.x releases. We reverted this in [#1113](chronotope/chrono#1113).
