Bugfix: datetime parsing and local timezones (#15544)
Hi,
This PR should close 3 issues
- [DMY date format is parsed inconsistently
#14123](https://github.com/nushell/nushell/issues/14123)
- [into datetime doesnt't work with --format and ignores user's locale
#11015](https://github.com/nushell/nushell/issues/11015)
- [into datetime: iinconsistent and incrrect behaviour regarding
timezones #13823](https://github.com/nushell/nushell/issues/13823)


# Description
- Allow to parse only dates or only times with --format
- Use local timezone depending on the input. Ex: I'm in France, so show
dates with +0100 in winter and +0200 in summer.

```nushell
# Concerning #13823

> "2020-01-01 12:00" | into datetime
Wed, 1 Jan 2020 12:00:00 +0100 (5 years ago)
# OK, it's my timezone in winter time

> "2020-06-01 12:00" | into datetime
Mon, 1 Jun 2020 12:00:00 +0200 (4 years ago)
# OK, it's my timezone in summertime

> ("2024-10-27 12:00" | into datetime) - ("2024-10-27 00:00" | into datetime)
13hr
# Ok, because we switched from summer to winter time on 2025-10-27, so there are actually 13h between midnight and noon

> "2020-01-01 12:00" | into datetime --format "%Y-%m-%d %H:%M"
Wed, 1 Jan 2020 12:00:00 +0100 (5 years ago)
# OK: timezone is assumed to be local, and +0100 is my timezone in winter

# Concerning #14123 and #11015
# Flexible parsing still works like before, which could be counter-intuitive, but it's flexible parsing
# with one difference: the timezone is local
> '12-01-2001' | into datetime
Sat, 1 Dec 2001 00:00:00 +0100 (23 years ago)
# OK, +0100 is my timezone in winter time. If I run it with nushell 0.103.0 in summer time, I get +0200
> '13-01-2001' | into datetime
Sat, 13 Jan 2001 00:00:00 +0100 (24 years ago)

## If you want, you can use the --format option to parse a date or a time (before, it had to be a date + time)
## Notice here again the timezone is correct depending on winter/summer time
~> "06.03.2023" | into datetime -f "%d.%m.%Y"
Mon, 6 Mar 2023 00:00:00 +0100 (2 years ago)
~> "06.03.2023" | into datetime -f "%m.%d.%Y"
Sat, 3 Jun 2023 00:00:00 +0200 (2 years ago)
> "10:00" | into datetime --format "%H:%M"
Thu, 10 Apr 2025 10:00:00 +0200 (9 hours ago)

Nushell core libraries and plugins

These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.

Foundational libraries are split into two kinds of crates:

  • Core crates - those crates that work together to build the Nushell language engine
  • Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.

Plugins are likewise also split into two types:

  • Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
  • Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
