Feature Parity is missing durations

[FoxxMD]

Durations are a standardized format and should be included.

• momentjs supports.
• date-fns does not officially, but there is a user-contributed workaround
• dayjs does not support
• luxon supports

[Goostavo]

Durations have three main function:

• type used to describe a duration to be summed without a date
• parser (example, parse HH:MM:DD)
• Display (ex. human readable display such as 32m 12s)

Alternatives to all:

I needed the parser, i've used this solution: Stackoverflow solution

About the display solution: humanize-duration on npm
