The RFC822, RFC850, and RFC1123 formats should be applied only to local times. Applying them to UTC times will use “UTC” as the time zone abbreviation, while strictly speaking those RFCs require the use of “GMT” in that case. In general RFC1123Z should be used instead of RFC1123 for servers that insist on that format, and RFC3339 should be preferred for new protocols. RFC3339, RFC822, RFC822Z, RFC1123, and RFC1123Z are useful for formatting; when used with time.Parse they do not accept all the time formats permitted by the RFCs and they do accept time formats not formally defined. The RFC3339Nano format removes trailing zeros from the seconds field and thus may not sort correctly once formatted.

Common durations. There is no definition for units of Day or larger to avoid confusion across daylight savings time zone transitions.
