Parsing a time string with a "Z" time zone using a time format that includes time zone seconds fails.
https://go.dev/play/p/FgeEzRinnL8
What did you see happen?
The call to time.Parse returned an error. For example, this code:
tm, err = time.Parse("2006-01-02T15:04:05Z070000", "2024-07-01T12:34:56Z")
fmt.Println(tm)
fmt.Println(err)
outputs:
0001-01-01 00:00:00 +0000 UTC
parsing time "2024-07-01T12:34:56Z" as "2006-01-02T15:04:05Z070000": cannot parse "Z" as "Z070000"
What did you expect to see?
The call to time.Parse to succeed and return a time with the UTC time zone location. For example, this code:
tm, err = time.Parse("2006-01-02T15:04:05Z070000", "2024-07-01T12:34:56Z")
fmt.Println(tm)
fmt.Println(err)
SHOULD output:
2024-07-01 12:34:56 +0000 UTC
