time: timezone name heuristic in Parse rejects MSK and MSD #3790
Description
by k.shutemov:
I found that that current heuristic for parsing stdTZ is too strict:
go/src/pkg/time/format.go
809 if len(value) >= 3 && value[2] == 'T' {
810 p, value = value[0:3], value[3:]
811 } else if len(value) >= 4 && value[3] == 'T' {
812 p, value = value[0:4], value[4:]
813 } else {
814 err = errBad
815 break
816 }
As you can see it only accepts timezone names with 'T' at end. It's not
correct: "MSK" is a valid timezone name.
