The log package defines a "standard logger" with some preconfigured flags to give you the date and time.
I modified your Playground link to have the same flags as the standard logger: https://play.golang.org/p/lch7YIbe6T I used the SetFlags method and set it to LstdFlags, which is equal to the flags used by the standard logger.
