Pedro Gimeno 89274f906a Improve /time command to allow time in h:m and omitting set
`/time set N` and `/time add N` work like before. The following extensions were added:

- `/time N`, `/time str`
  - same as `/time set N` and `/time set str` respectively
- `/time h:m`, `/time set h:m`
  - allows setting a specific time in hour:minutes format
- `/time add h:m`
  - adds a specific number of hours and minutes to the time
