Class Method Details

def days_in_month(year, month)
  (Date.new(year, 12, 31) << (12-month)).day
end

.fixate(y, m = 1, d = 1, h = 0, mi = 0, s = 0, &block) ⇒ Object

Fixes the relative time by which all of Timetastic operations are carried out for the duration of the given block.

Mainly used for tests and gem development.

An alternative way to ‘fix’ the time is to directly use the exposed attribute Timetastic#fixed_time, ie:

> Timetastic.fixed_time = Time.new(Time.now.year, 6, 1)

You can simply set the attribute to nil to reset the time back to Time.now
