allow parsing of human readable datetimes (#11051)
# Description This PR adds the ability to parse human readable datetime strings as part of the `into datetime` command. I added a new `-n`/`--list-human` parameter that produces this list to give the user an idea of what is supported. ```nushell ❯ into datetime --list-human ╭#─┬parseable human datetime examples┬───result───╮ │0 │Today 18:30 │in 8 hours │ │1 │2022-11-07 13:25:30 │a year ago │ │2 │15:20 Friday │in 3 days │ │3 │This Friday 17:00 │in 3 days │ │4 │13:25, Next Tuesday │in a week │ │5 │Last Friday at 19:45 │3 days ago │ │6 │In 3 days │in 2 days │ │7 │In 2 hours │in 2 hours │ │8 │10 hours and 5 minutes ago │10 hours ago│ │9 │1 years ago │a year ago │ │10│A year ago │a year ago │ │11│A month ago │a month ago │ │12│A week ago │a week ago │ │13│A day ago │a day ago │ │14│An hour ago │an hour ago │ │15│A minute ago │a minute ago│ │16│A second ago │now │ │17│Now │now │ ╰#─┴parseable human datetime examples┴───result───╯ ``` Or with `$env.config.datetime_format.table` set. ```nushell ❯ into datetime --list-human ╭#─┬parseable human datetime examples┬──────result───────╮ │0 │Today 18:30 │11/14/23 06:30:00PM│ │1 │2022-11-07 13:25:30 │11/07/22 01:25:30PM│ │2 │15:20 Friday │11/17/23 03:20:00PM│ │3 │This Friday 17:00 │11/17/23 05:00:00PM│ │4 │13:25, Next Tuesday │11/21/23 01:25:00PM│ │5 │Last Friday at 19:45 │11/10/23 07:45:00PM│ │6 │In 3 days │11/17/23 10:12:54AM│ │7 │In 2 hours │11/14/23 12:12:54PM│ │8 │10 hours and 5 minutes ago │11/14/23 12:07:54AM│ │9 │1 years ago │11/13/22 10:12:54AM│ │10│A year ago │11/13/22 10:12:54AM│ │11│A month ago │10/15/23 11:12:54AM│ │12│A week ago │11/07/23 10:12:54AM│ │13│A day ago │11/13/23 10:12:54AM│ │14│An hour ago │11/14/23 09:12:54AM│ │15│A minute ago │11/14/23 10:11:54AM│ │16│A second ago │11/14/23 10:12:53AM│ │17│Now │11/14/23 10:12:54AM│ ╰#─┴parseable human datetime examples┴──────result───────╯ ``` # User-Facing Changes <!-- List of all changes that impact the user experience here.
