In ourĬurrent pattern usage, not all letters have meanings. Resulting text even though they are not enclosed in single quotes. Instance, characters like ':', '.', ' ', '#' and will appear in the (Text & Number): 3 or over, use text, otherwise use number.Īny characters not in the pattern will be treated as quoted text. Other fields, fractional seconds are padded on the right with zero. Specially that is, if the count of 'y' is 2, the Year will be truncated toĢ digits. less than 3-use numeric form if one exists.3 pattern letters-use short or abbreviated form if one exists.4 or more pattern letters-use full form,.5 pattern letters-use narrow form for standalone.The count of pattern letters determine the format. V time zone (generic) (Text) Pacific Time The following characters are reserved and currently are unimplemented: Symbol Meaning Presentation Example L standalone month (Text & Number) July & 07 M month in year (Text & Number) July & 07 The following characters are available in explicit patterns: Symbol Meaning Presentation Example So it is preferable to use the skeletons. The behaviour of the 'j' skeleton, which prints 24 hour or 12 hour timeĪccording to the conventions of the locale, and also includes am/pm markers But there isn't a way in an explicit pattern to get Pattern the letters 'H' and 'h' are available for 24 hour and 12 hour timeįormats respectively. This can be used for formats that don't have a skeleton available,īut these will not adapt to different locales. HOUR_MINUTE_GENERIC_TZ jmv (not yet implemented)Įxamples Using the US Locale: Pattern ResultĭateFormat.yMMMMd('en_US') -> July 10, 1996ĭateFormat.Hm() -> 17:08 // force 24 hour timeĮxplicit Pattern Syntax: Formats can also be specified with a pattern It's also possible to pass the skeleton as a string, but theĬonstructor is preferred. The supported set of skeletons is as follows.įor each skeleton there is a named constructor that can be used to create Skeletons: These can be specified either as the ICU constant name or as the Which can also adapt to different locales and is preferred where available. This library uses the ICU/JDK date/time pattern specification both forĬomplete format specifications and also the abbreviated 'skeleton' form Once we have the locale data, we need to specify the particular format. InitializeDateFormatting('pt_BR', null).then((_) => runM圜ode()) import 'package:intl/date_symbol_data_http_request.dart' Server using the XmlHttpRequest mechanism. If we are running in a browser, we may want to read the data from the InitializeDateFormatting('de_DE', null).then((_) => runM圜ode()) import 'package:intl/date_symbol_data_file.dart' If we are running outside of a browser, we may want to read the dataįrom files in the file system. InitializeDateFormatting('fr_FR', null).then((_) => runM圜ode()) import 'package:intl/date_symbol_data_local.dart' Library that contains data for all the locales. The easiest option is that the data may be available locally, imported in a The result of the future isn't important, but theĭata for that locale is available to the date formatting and parsing once it Method must be called and will return a future that is complete once the In all cases, the 'initializeDateFormatting' This can currently be done in one of three ways, determined by print(DateFormat.yMMMd().format(DateTime.now())) īut for other locales, the formatting data for the locale must be Locales include month name, weekname, field, order, etc.įormatting dates in the default 'en_US' format does not require any We also allow the user to use any customized pattern to parse or formatĭate-time strings under certain locales. That vary across locales include month name, week name, field order, etc. Well as specify a customized pattern under certain locales. It allows the user to choose from a set of standard date time formats as DateFormat is for formatting and parsing dates in a locale-sensitive
