strftime
strftime for JavaScript, works in Node.js and browsers, supports localization. Most standard specifiers from C are supported as well as some other extensions from Ruby.
Installation
npm install strftime
Usage
var strftime = require('strftime')
console.log(strftime('%B %d, %y %H:%M:%S')) // => April 28, 2011 18:21:08
console.log(strftime('%F %T', new Date(1307472705067))) // => 2011-06-07 18:51:45If you want to localize it:
var strftime = require('strftime')
var it_IT = {
days: [ 'domenica', 'lunedi', 'martedi', 'mercoledi', 'giovedi', 'venerdi', 'sabato' ],
shortDays: [ 'dom', 'lun', 'mar', 'mer', 'gio', 'ven', 'sab' ],
months: [ 'gennaio', 'febbraio', 'marzo', 'aprile', 'maggio', 'giugno', 'luglio',
'agosto', 'settembre', 'ottobre', 'novembre', 'dicembre' ],
shortMonths: [ 'gen', 'feb', 'mar', 'apr', 'mag', 'giu', 'lug', 'ago',
'set', 'ott', 'nov', 'dic' ],
AM: 'AM',
PM: 'PM'
}
console.log(strftime('%B %d, %y %H:%M:%S', it_IT)) // => aprile 28, 2011 18:21:08
console.log(strftime('%B %d, %y %H:%M:%S', new Date(1307472705067), it_IT)) // => giugno 7, 2011 18:51:45And if you don't want to pass a localization object every time you can get a localized strftime function like so:
var strftime = require('strftime')
var it_IT = { /* same as above */ }
var strftime_IT = strftime.localizedStrftime(it_IT)
console.log(strftime_IT('%B %d, %y %H:%M:%S')) // aprile 28, 2011 18:21:08Supported Specifiers
Extensions from Ruby are noted in the following list.
Unsupported specifiers are rendered without the percent sign.
e.g. %q becomes q. Use %% to get a literal % sign.
- A: full weekday name
- a: abbreviated weekday name
- B: full month name
- b: abbreviated month name
- C: AD century (year / 100), padded to 2 digits
- D: equivalent to
%m/%d/%y - d: day of the month, padded to 2 digits (01-31)
- e: day of the month, padded with a leading space for single digit values (1-31)
- F: equivalent to
%Y-%m-%d - H: the hour (24-hour clock), padded to 2 digits (00-23)
- h: the same as %b (abbreviated month name)
- I: the hour (12-hour clock), padded to 2 digits (01-12)
- j: day of the year, padded to 3 digits (001-366)
- k: the hour (24-hour clock), padded with a leading space for single digit values (0-23)
- L: the milliseconds, padded to 3 digits [Ruby extension]
- l: the hour (12-hour clock), padded with a leading space for single digit values (1-12)
- M: the minute, padded to 2 digits (00-59)
- m: the month, padded to 2 digits (01-12)
- n: newline character
- P: "am" or "pm" in lowercase [Ruby extension]
- p: "AM" or "PM"
- R: equivalent to
%H:%M - r: equivalent to
%I:%M:%S %p - S: the second, padded to 2 digits (00-60)
- s: the number of seconds since the Epoch, UTC
- T: equivalent to
%H:%M:%S - t: tab character
- U: week number of the year, Sunday as the first day of the week, padded to 2 digits (00-53)
- u: the weekday, Monday as the first day of the week (1-7)
- v: equivalent to
%e-%b-%Y - W: week number of the year, Monday as the first day of the week, padded to 2 digits (00-53)
- w: the weekday, Sunday as the first day of the week (0-6)
- Y: the year with the century
- y: the year without the century (00-99)
- Z: the time zone name, replaced with an empty string if it is not found
- z: the time zone offset from UTC, with a leading plus sign for UTC and zones east of UTC and a minus sign for those west of UTC, hours and minutes follow each padded to 2 digits and with no delimiter between them
For more detail see man 3 strftime as the format specifiers should behave
identically. If behaviour differs please file a bug.
Any specifier can be modified with -, _, or 0 as well, as in Ruby.
Using %- will omit any leading zeroes or spaces, %_ will force spaces
for padding instead of the default, and %0 will force zeroes for padding.
There's some redundancy here as %-d and %e have the same result, but it
solves some awkwardness with formats like %l.
