The default internal encoding is not taken into account to encode
timezone name.

[Bug #20797] Check seconds in UTC offset as well as minutes

2024-09-06T06:53:46+00:00

In short, get rid of division and modulo of negative integers.

Move Time#xmlschema in core and optimize it

2024-09-05T17:23:12+00:00

[Feature #20707]

Converting Time into RFC3339 / ISO8601 representation is an significant
hotspot for applications that serialize data in JSON, XML or other formats.

By moving it into core we can optimize it much further than what `strftime` will
allow.

[DOC] State timezone info in the string wins `in:` keyword

2023-11-24T10:38:55+00:00

Use embedded TypedData for Time objects

2023-11-07T20:48:06+00:00

This drops the total size of a Time object from 86 bytes to 80 bytes.

Running the benchmark benchmark/time_now.yml, this commit improves
performance of Time.now by about 30%:

```
  Time.now
Branch:  13159405.4 i/s
Master:  10036908.7 i/s - 1.31x  slower

  Time.now(in: "+09:00")
Branch:   2712172.6 i/s
Master:   2138637.9 i/s - 1.27x  slower
```

It also decreases memory usage by about 20%:

```
ary = 10_000_000.times.map { Time.now }

puts `ps -o rss= -p #{$$}`
```

Remove --disable-gems for assert_separately

2023-08-03T00:11:08+00:00

assert_separately adds --disable=gems so we don't need to add
--disable-gems when calling assert_separately.
