Fixed-format item types.

They have their own rules of formatting and parsing. Otherwise noted, they print in the specified cases but parse case-insensitively.

## Variants

`ShortMonthName`

Abbreviated month names.

Prints a three-letter-long name in the title case, reads the same name in any case.

`LongMonthName`

Full month names.

Prints a full name in the title case, reads either a short or full name in any case.

`ShortWeekdayName`

Abbreviated day of the week names.

Prints a three-letter-long name in the title case, reads the same name in any case.

`LongWeekdayName`

Full day of the week names.

Prints a full name in the title case, reads either a short or full name in any case.

`LowerAmPm`

AM/PM.

Prints in lower case, reads in any case.

`UpperAmPm`

AM/PM.

Prints in upper case, reads in any case.

`Nanosecond`

An optional dot plus one or more digits for left-aligned nanoseconds. May print nothing, 3, 6 or 9 digits according to the available accuracy. See also `Numeric::Nanosecond`.

`Nanosecond3`

Same as `Nanosecond` but the accuracy is fixed to 3.

`Nanosecond6`

Same as `Nanosecond` but the accuracy is fixed to 6.

`Nanosecond9`

Same as `Nanosecond` but the accuracy is fixed to 9.

`TimezoneName`

Timezone name.

It does not support parsing, its use in the parser is an immediate failure.

`TimezoneOffsetColon`

Offset from the local time to UTC (`+09:00` or `-04:00` or `+00:00`).

In the parser, the colon can be omitted and/or surrounded with any amount of whitespace. The offset is limited from `-24:00` to `+24:00`, which is the same as `FixedOffset`’s range.

`TimezoneOffsetColonZ`

Offset from the local time to UTC (`+09:00` or `-04:00` or `Z`).

In the parser, the colon can be omitted and/or surrounded with any amount of whitespace, and `Z` can be either in upper case or in lower case. The offset is limited from `-24:00` to `+24:00`, which is the same as `FixedOffset`’s range.

`TimezoneOffset`

Same as `TimezoneOffsetColon` but prints no colon. Parsing allows an optional colon.

`TimezoneOffsetZ`

Same as `TimezoneOffsetColonZ` but prints no colon. Parsing allows an optional colon.

`RFC2822`

RFC 2822 date and time syntax. Commonly used for email and MIME date and time.

`RFC3339`

RFC 3339 & ISO 8601 date and time syntax.

`Internal(InternalFixed)`

Internal uses only.

This item exists so that one can add additional internal-only formatting without breaking major compatibility (as enum variants cannot be selectively private).
