Numeric item types. They have associated formatting width (FW) and parsing width (PW).

The formatting width is the minimal width to be formatted. If the number is too short, and the padding is not Pad::None, then it is left-padded. If the number is too long or (in some cases) negative, it is printed as is.

The parsing width is the maximal width to be scanned. The parser only tries to consume from one to given number of digits (greedily). It also trims the preceding whitespaces if any. It cannot parse the negative number, so some date and time cannot be formatted then parsed with the same formatting items.

Variants

Year	Full Gregorian year (FW=4, PW=infinity). May accept years before 1 BCE or after 9999 CE, given an initial sign.
YearDiv100	Gregorian year divided by 100 (century number; FW=PW=2). Implies the non-negative year.
YearMod100	Gregorian year modulo 100 (FW=PW=2). Cannot be negative.
IsoYear	Year in the ISO week date (FW=4, PW=infinity). May accept years before 1 BCE or after 9999 CE, given an initial sign.
IsoYearDiv100	Year in the ISO week date, divided by 100 (FW=PW=2). Implies the non-negative year.
IsoYearMod100	Year in the ISO week date, modulo 100 (FW=PW=2). Cannot be negative.
Month	Month (FW=PW=2).
Day	Day of the month (FW=PW=2).
WeekFromSun	Week number, where the week 1 starts at the first Sunday of January (FW=PW=2).
WeekFromMon	Week number, where the week 1 starts at the first Monday of January (FW=PW=2).
IsoWeek	Week number in the ISO week date (FW=PW=2).
NumDaysFromSun	Day of the week, where Sunday = 0 and Saturday = 6 (FW=PW=1).
WeekdayFromMon	Day of the week, where Monday = 1 and Sunday = 7 (FW=PW=1).
Ordinal	Day of the year (FW=PW=3).
Hour	Hour number in the 24-hour clocks (FW=PW=2).
Hour12	Hour number in the 12-hour clocks (FW=PW=2).
Minute	The number of minutes since the last whole hour (FW=PW=2).
Second	The number of seconds since the last whole minute (FW=PW=2).
Nanosecond	The number of nanoseconds since the last whole second (FW=PW=9). Note that this is not left-aligned; see also Fixed::Nanosecond.
Timestamp	The number of non-leap seconds since January 1, 1970 0:00:00 UTC (FW=1, PW=infinity).
