This adds a new `std` feature to chrono that is enabled by default. By
deactivating this feature via `default-features = false` you can now use
chrono in applications that don't use the standard library. The `serde`
feature is supported as well.
Resolves#336
The internal, tz-independent timestamp was valid, but since the timezone offset
could change as you add or subtract a second or two you would get
nonsense/nonexistent times when you observed them.
Fixes#318
This patch fixes the case where a negative millisecond offset is passed
to Timezone::timestamp_millis and timestamp_millis_opt and adds a test
case for it. Without this patch, calling timestamp_offset with a
negative value will panic with an overflow like this:
```
---- tests::test_parse_samples stdout ----
thread 'tests::test_parse_samples' panicked at 'attempt to multiply with
overflow',

```
Documentation added to both `impl`s and functions so that they are
visible to both users perusing the online documentation and in
autocomplete/intellisense engines.
And fail CI in the future if `make readme` isn't run when it is needed.
CC conversation in #185, where the README didn't get updated for a year after
lib.rs was improved.
