#date_between?(date, from, to) ⇒ Boolean

Tests whether the date is between from and to. Returns true then otherwise false. Time, from and to are Time objects as retrieved from Time.now or Time.local(2013,“apr”,13,10,50,0). Alternatively time strings can be provided in the form of “2013-04-13”.

Returns:

  • (Boolean)

Raises:

  • (ArgumentError)

#extract_time(time_string, time = false) ⇒ Object

Extracts the time out of a time string. Accepts ‘today’, ‘tomorrow’, ‘yesterday’ or a date in the form ‘YYYY-MM-DD’. Returns the date contained in the time_string or if time = true in a Time object
