Regarding "cannot use time.Now() (type time.Time) as type "

Question

Get "cannot use time.Now() (type time.Time) as type typetime in field value" with below type definition

import ("time")

type typetime time.Time 
type Friends struct {
   Name string
   Birthday typetime
}

John := Friends{Name:"John", Birthday:time.Now()}

If I replace typetime with direct type form (time.Time), there is no problem. what is GO's rule behind?? :>

Answer 1

time.Time and typetime are different types (though they have the same underlying representations) so you need to convert the type.

John := Friends{Name: "John", Birthday: typetime(time.Now())}
