Hello o/

I like to use nushell for date/duration/filesize conversions, but there is something that I need from time to time that seems to be unavailable at the moment:

• converting to a subset of the value, like hours to milliseconds to get the total number of milliseconds in a number of hours (~ 1hr | get total_ms => 3_600_000ms)
• getting a superset of the value, like seconds to hours to get the number of hours in a (potentially large) number of seconds (~ 123456sec | get total_hours => 34hr)

These example could be useful for duration but could also be useful for filesize or date objects 🤔

I've found that we can do 123456sec | into record to get as data the information in the humanized form 1day 10hr 17min 36sec but even here we are missing some fields like milliseconds or weeks that could be needed when manipulating unknown values.

Describe the solution you'd like

Something like this:
1wk | into record | get total_hours
(date now) - 2019-05-01 | into record | get total_days
12sec | into record | get hours (0)

Describe alternatives you've considered

I could handle all edge cases, do sums myself, but it feels like a huge pain for seemingly simple operations 🤔
