# Description
Converting a date as a human readable string to a datetime:
- currently: using the ``into datetime`` command
- after this change: using ``date from-human`` command
Also moved the ``--list-human`` flag to the new command.
# User-Facing Changes
- Users have to use a new command for parsing human readable datetimes.
Result:
```nushell
~> date from-human --list

# Description
This PR seeks to fix an error in `polars as-datetime` where timezone
information is entirely ignored. This behavior raises a host of silent
errors when dealing with datetime conversions (see example below).
## Current Implementation
Timezones are entirely ignored and datetimes with different timezones
are converted to the same naive datetimes even when the user
specifically indicates that the timezone should be parsed. For example,
"2021-12-30 00:00:00 +0000" and "2021-12-30 00:00:00 -0400" will both be
parsed to "2021-12-30 00:00:00" even when the format string specifically
includes "%z".
```
$ ["2021-12-30 00:00:00 +0000" "2021-12-30 00:00:00 -0400"] | polars into-df | polars as-datetime "%Y-%m-%d %H:%M:%S %z"
╭───┬───────────────────────╮

│ 0 │ 12/30/2021 12:00:00AM │
│ 1 │ 12/30/2021 12:00:00AM │ <-- Same datetime even though the first is +0000 and second is -0400
╰───┴───────────────────────╯
$ ["2021-12-30 00:00:00 +0000" "2021-12-30 00:00:00 -0400"] | polars into-df | polars as-datetime "%Y-%m-%d %H:%M:%S %z" | polars schema
╭──────────┬──────────────╮
│ datetime │ datetime<ns> │
╰──────────┴──────────────╯
```
## New Implementation
Datetimes are converted to UTC and timezone information is retained.
```
$ "2021-12-30 00:00:00 +0000" "2021-12-30 00:00:00 -0400"] | polars into-df | polars as-datetime "%Y-%m-%d %H:%M:%S %z"
╭───┬───────────────────────╮
│ # │ datetime │
├───┼───────────────────────┤
│ 0 │ 12/30/2021 12:00:00AM │
│ 1 │ 12/30/2021 04:00:00AM │ <-- Converted to UTC
╰───┴───────────────────────╯
$ ["2021-12-30 00:00:00 +0000" "2021-12-30 00:00:00 -0400"] | polars into-df | polars as-datetime "%Y-%m-%d %H:%M:%S %z" | polars schema
╭──────────┬───────────────────╮
│ datetime │ datetime<ns, UTC> │
╰──────────┴───────────────────╯
```
The user may intentionally ignore timezone information by setting the
`--naive` flag.
```
$ ["2021-12-30 00:00:00 +0000" "2021-12-30 00:00:00 -0400"] | polars into-df | polars as-datetime "%Y-%m-%d %H:%M:%S %z" --naive

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
`polars as-datetime` will now account for timezone information and
return type `datetime<ns,UTC>` rather than `datetime<ns>` by default.
The user can replicate the previous behavior by setting `--naive`.

Consider PATH when checking for potential_nuscript_in_windows to allow
executing scripts which are in PATH without having to full path address
them. It previously only checked the current working directory so only
relative paths to cwd and full path worked.
The current implementation runs this then through cmd.exe /D /C which
can run it with assoc and ftype set for nushell scripts.
We could instead run it through nu as `std::env::current_exe()` avoiding
the cmd call and the need for assoc and ftype (see:
8b25173f02).
But ive left the current implementation for this intact to not change
implementation details, avoid a bigger change and leave this open for
discussion here since im not sure if this has any major implications.
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This

This would now run every external command through PATH an additional
time on windows, so potentially twice. I dont think this has any bigger
effect.

Issue #9887 which can be closed after this is merged.
# Description
This allows the "into duration" command to accept floats as inputs.
Examples:
<img width="767" alt="image"
src="https://github.com/user-attachments/assets/da181f2a-7ad6-4efb-a6db-f9c6d8929c71"
/>
<img width="710" alt="image"
src="https://github.com/user-attachments/assets/78623a39-33ad-42a0-9324-a147be86f95c"
/>
**How it works:**
Using strings, like `"1.234sec" | into duration`, is already working, so
if a user inputs `1.234 | into duration --sec`, I just convert this back
to a string and use the previous conversion functions.
**Limitations:**
there are some limitation to using floats, but it's a general limitation
that is already present for other use cases:
- only 3 digits are taken into account in the decimal part
- floating durations in nano seconds are always floored and not rounded

# Description
This PR expands the `dtype` parameter of the `polars cast` command to
include `decimal<precision, scale>` type. Setting precision to "*" will
compel inferring the value. Note, however, setting scale to a
non-integer value will throw an explicit error (the underlying polars
crate assigns scale = 0 in such a case, but I opted for throwing an
error instead). .

# Description
There's been much debate about whether to keep human-date-parser in
`into datetime`. We saw recently that a new version of the crate was
released that addressed some of our concerns. This PR is to make it
easier to test those fixes.
