Make date-constructor test more portable

The timezone offset in effect on Dec 25, 1995 won't be applicable
in years far away from 1995 (e.g. year 1111).

Calculate the timezone offset in Feb 1, 1995 and run other tests
on the same day.

This issue has been hidden because the current implementation doesn't
take into account the history of timezone offset changes(crbug.com/3547),
but was exposed when a correct implementation based on ICU was tried.

// In Firefox, the results of the following tests are timezone-dependent, which likely implies that the implementation is not quite correct.
// Our results are even worse, though, as the dates are clipped: (new Date(1111, 1201).getTime()) == (new Date(1111, 601).getTime())
