Expand description
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).
