Overview

Specifies the format to convert a Time to and from a String.

The pattern of a format is a String with directives. Directives being with a percent (%) character. Any text not listed as a directive will be passed/parsed through the output/input string.

The directives are:

• %a: short day name (Sun, Mon, Tue, ...)
• %^a: short day name, upcase (SUN, MON, TUE, ...)
• %A: day name (Sunday, Monday, Tuesday, ...)
• %^A: day name, upcase (SUNDAY, MONDAY, TUESDAY, ...)
• %b: short month name (Jan, Feb, Mar, ...)
• %^b: short month name, upcase (JAN, FEB, MAR, ...)
• %B: month name (January, February, March, ...)
• %^B: month name, upcase (JANUARY, FEBRUARY, MARCH, ...)
• %c: date and time (Tue Apr 5 10:26:19 2016)
• %C: year divided by 100
• %d: day of month, zero padded (01, 02, ...)
• %-d: day of month (1, 2, ..., 31)
• %D: date (04/05/16)
• %e: day of month, blank padded (" 1", " 2", ..., "10", "11", ...)
• %F: ISO 8601 date (2016-04-05)
• %g: week-based calendar year modulo 100 (00..99)
• %G: week-based calendar year (0001..9999)
• %h: (same as %b) short month name (Jan, Feb, Mar, ...)
• %H: hour of the day, 24-hour clock, zero padded (00, 01, ..., 24)
• %I: hour of the day, 12-hour clock, zero padded (00, 01, ..., 12)
• %j: day of year, zero padded (001, 002, ..., 365)
• %k: hour of the day, 24-hour clock, blank padded (" 0", " 1", ..., "24")
• %l: hour of the day, 12-hour clock, blank padded (" 0", " 1", ..., "12")
• %L: milliseconds, zero padded (000, 001, ..., 999) (same as %3N)
• %m: month number, zero padded (01, 02, ..., 12)
• %_m: month number, blank padded (" 1", " 2", ..., "12")
• %-m: month number (1, 2, ..., 12)
• %M: minute, zero padded (00, 01, 02, ..., 59)
• %3N: milliseconds, zero padded (000, 001, ..., 999) (same as %L)
• %6N: microseconds, zero padded (000000, 000001, ..., 999999)
• %9N: nanoseconds, zero padded (000000000, 000000001, ..., 999999999)
• %N: second fraction, zero padded. (Same as %9N but may consume more than 9 digits while parsing)
• %p: am-pm (lowercase)
• %P: AM-PM (uppercase)
• %r: 12-hour time (03:04:05 AM)
• %R: 24-hour time (13:04)
• %s: seconds since unix epoch (see Time#to_unix)
• %S: seconds, zero padded (00, 01, ..., 59)
• %T: 24-hour time (13:04:05)
• %u: day of week (Monday is 1, 1..7)
• %V: ISO calendar week number of the week-based year (01..53)
• %w: day of week (Sunday is 0, 0..6)
• %x: (same as %D) date (04/05/16)
• %X: (same as %T) 24-hour time (13:04:05)
• %y: year modulo 100
• %Y: year, zero padded
• %z: time zone offset from UTC as hour and minute with no separator (+0900)
• %:z: time zone offset from UTC as hour and minute separated by colon (+09:00)
• %::z: time zone offset from UTC as hour, minute and second separated by colon (+09:00:00)
• %Z: location name or offset (e.g. Europe/Berlin)
• %^Z: abbreviated time zone identifier or offset (e.g. CET)
