Description
Currently the test suite may fail to pass, unless you run it with TZ=UTC ./miri test. This is because the localtime_r shim reads the TZ variable from the host on this line:
| // Convert that to local time, then return the broken-down time value. |
|---|
| let dt: DateTime<Local> = DateTime::from(dt_utc); |
In other words, this test code is ineffective:
| // Set timezone to GMT. |
|---|
| let key = "TZ"; |
| env::set_var(key, "GMT"); |
I'm going to look into this.
