Overview

This class handels various time- and date-specific behaviour in a friendly way.

Examples

datet = Datet.new #=> 2012-05-03 20:35:16 0200 datet = Datet.new(Time.now) #=> 2012-05-03 20:35:16 0200 datet.months + 5 #=> 2012-10-03 20:35:16 0200 datet.days 64 #=> 2012-12-06 20:35:16 +010

Constructor Details

#initialize(*args) ⇒ Datet

Initializes the object. Default is the current time. A time-object can be given.

Examples

datet = Datet.new #=> Datet-object with the current date and time.

time = Time.new datet = Datet.new(time) #=> Datet-object with the date and time from the given Time-object.

datet = Datet.new(1985, 06, 17) #=> Datet-object with the date 1985-06-17. datet = Datet.new(1985, 06, 17, 10) #=> Datet-object with the date 1985-06-17 10:00:00

datet = Datet.new(1985, 06, 35) #=> Datet-object with the date 1985-07-05 00:00:00. Notice the invalid day of 35 was automatically converted to the right date.

Class Method Details

.arg_to_datet(datet) ⇒ Object

Turns the given argument into a new Datet-object. Helps compare datet- to time-objects.

Examples

time = Datet.arg_to_time(datet) #=> <Datet>-object time = Datet.arg_to_time(Datet.now) #=> <Datet>-object

end

.arg_to_time(datet) ⇒ Object

Turns the given argument into a new Time-object.

Examples

.days(args = nil) ⇒ Object

Returns a hash with the day-number as value (starting with 1 for monday). It uses the method “_” to translate the months names.

Examples

Datet.days #=> 1=>“Monday”, 2=>“Tuesday”, 3=>“Wednesday”, 4=>“Thursday”, 5=>“Friday”, 6=>“Saturday” Datet.days(:mfirst => true) #=> 1=>“Tuesday”, 2=>“Wednesday”, 3=>“Thursday”, 4=>“Friday”, 5=>“Saturday”, 6=>“Sunday”
