Parse a date and time from a string
Given the string
"2008-05-06 13:29", parse it as a date representing 6th March, 2008 1:29:00pm in the local time zone.
groovy
def date = new SimpleDateFormat("yyy-MM-dd HH:mm").parse("2008-05-06 13:29")
def date = Date.parse("yyy-MM-dd HH:mm", "2008-05-06 13:29")
erlang
% AFAIK, no datetime-parsing library exists; 'parse_to_datetime' is a simplistic, problem-specific hack
LocalDateTime = erlang:universaltime_to_localtime(parse_to_datetime("2008-05-06 13:29:34")),
LocalDateTime = erlang:universaltime_to_localtime(parse_to_datetime("2008-05-06 13:29:34")),
clojure
(.. (SimpleDateFormat. "yyyy-MM-dd HH:mm")
(parse "2008-05-06 13:29"))
(parse "2008-05-06 13:29"))
Display information about a date
Display the day of month, day of year, month name and day name of the day 8 days from now.
groovy
use (TimeCategory) {
eight_days_time = 1.week.from.now + 1.day
}
println eight_days_time[DAY_OF_MONTH]
println eight_days_time.format('d') // alternative to above
println eight_days_time[DAY_OF_YEAR]
println eight_days_time.format('MMMM')
println eight_days_time.format('EEEE')
eight_days_time = 1.week.from.now + 1.day
}
println eight_days_time[DAY_OF_MONTH]
println eight_days_time.format('d') // alternative to above
println eight_days_time[DAY_OF_YEAR]
println eight_days_time.format('MMMM')
println eight_days_time.format('EEEE')
clojure
(let [cal (Calendar/getInstance)]
(.add cal Calendar/DAY_OF_YEAR 8)
(println (.format (SimpleDateFormat. "d, D, MMMM, EEEE")
(.getTime cal))))
(.add cal Calendar/DAY_OF_YEAR 8)
(println (.format (SimpleDateFormat. "d, D, MMMM, EEEE")
(.getTime cal))))
Display a date in different locales
Display a language/locale friendly version of New Year's Day for 2009 for several languages/locales. E.g. for languages English, French, German, Italian, Dutch the output might be something like:
Thursday, January 1, 2009
jeudi 1 janvier 2009
giovedì 1 gennaio 2009
Donnerstag, 1. Januar 2009
donderdag 1 januari 2009
(Indicate in comments where possible if any language specific or operating system configuration needs to be in place.)
Thursday, January 1, 2009
jeudi 1 janvier 2009
giovedì 1 gennaio 2009
Donnerstag, 1. Januar 2009
donderdag 1 januari 2009
(Indicate in comments where possible if any language specific or operating system configuration needs to be in place.)
groovy
cal = Calendar.instance
cal.set(2009, JANUARY, 1)
[ENGLISH, FRENCH, ITALIAN, GERMAN, new Locale('nl')].each { lang ->
println getDateInstance(FULL, lang).format(cal.time)
}
// relies on Java I18N capabilities which supports many locales, see:
// http://java.sun.com/javase/technologies/core/basic/intl/
// available Locales may depend on your version of Java and/or
// operating system and/or installed fonts
cal.set(2009, JANUARY, 1)
[ENGLISH, FRENCH, ITALIAN, GERMAN, new Locale('nl')].each { lang ->
println getDateInstance(FULL, lang).format(cal.time)
}
// relies on Java I18N capabilities which supports many locales, see:
// http://java.sun.com/javase/technologies/core/basic/intl/
// available Locales may depend on your version of Java and/or
// operating system and/or installed fonts
clojure
(let [time (.getTime (GregorianCalendar. 2009 Calendar/JANUARY 1))]
(doseq [locale ["en" "fr" "it" "de" "nl"]]
(println (.format (DateFormat/getDateInstance DateFormat/FULL
(Locale. locale))
time))))
(doseq [locale ["en" "fr" "it" "de" "nl"]]
(println (.format (DateFormat/getDateInstance DateFormat/FULL
(Locale. locale))
time))))
Display the current date and time
Create a Date object representing the current date and time. Print it out.
If you can also do this without creating a Date object you can show that too.
If you can also do this without creating a Date object you can show that too.
groovy
println new Date()
erlang
io:format("~p~n", [calendar:local_time()])
clojure
(import 'java.util.Date)
(println (str (Date.)))
(println (str (Date.)))
