How to access global variables

Question

How do I access a variable that was declared/init in my main.go in a different .go package/file? Keeps telling me that the variable is undefined (I know that global variables are bad but this is just to be used as a timestamp)

in main.go

var StartTime = time.Now()
func main(){...}

trying to access StartTime in a different .go file but keep getting StartTime undefined

Answer 1

I would "inject" the starttime variable instead, otherwise you have a circular dependency between the packages.

main.go

var StartTime = time.Now()
func main() {
   otherPackage.StartTime = StartTime
}

otherpackage.go

var StartTime time.Time
