Summary

glab token create shows misleading/incorrect help texts about duration

Steps to reproduce

$ glab token create -h
...
  FLAGS  
    -D --duration      Sets the token duration, in hours. Maximum of 8760. Examples: 24h, 168h, 504h. (720h0m0s)

$ glab token create --user @me --scope read_registry -D 8 tmp
          
   ERROR  
          
  Invalid argument "8" for "-D, --duration" flag: time: missing unit in duration "8".    

$ glab token create --user @me --scope read_registry -D 8h tmp 
          
   ERROR  
          
  Duration must be in days.. 

$ glab token create --user @me --scope read_registry -D 1d tmp  
          
   ERROR  
          
  Invalid argument "1d" for "-D, --duration" flag: time: unknown unit "d" in duration "1d".

What is the current bug behavior?

-h says duration is in hours but trying to set in hours results in error that is must in days. Also when -h specifically mentions hours then I would assume it would work without unit but that doesn't work. Also d doesn't work as day units.

What is the expected correct behavior?

Fix -h text to mention it requiring full days and say unit is required. Preferably use days instead of hours.

Fix validation error to mention it must be in full days.

Fix d to work as unit of days.

And since go Duration doesn't support anything larger than hour due to different length days (i.e. daylight savings time) you need to add own parser for this.
