NAME

6       Time::Warp - control over the flow of time
7

SYNOPSIS

9           use Time::Warp qw(scale to time);
10
11           to(time + 5);  # 5 seconds ahead
12           scale(2);      # make time flow twice normal
13

DESCRIPTION

15       Our external experience unfolds in 3 1/2 dimensions (time has a
16       dimensionality of 1/2).  The Time::Warp module offers developers
17       control over the measurement of time.

API

20       •   to($desired_time)
21
22           The theory of relativity asserts that all physical laws are
23           enforced relative to the observer.  Since the starting point of
24           time is arbitrary, it is permissible to change it.  This has the
25           effect of making it appear as if time is moving forwards or
26           backward instanteously.  For example, on some types of operating
27           systems time starts at Wed Dec 31 19:00:00 1969 (this will likely
28           change as we approach 2030 and with the acceptance of 64-bit CPUs).
29
30             to(time + 60*60);       # 1 hour ahead
31
32       •   scale($factor)
33
34           Changes the speed at which time is progressing.
35
36             scale(scale * 2);   # double the speed of time
37
38           Note that it is not possible to stop time or cause it to reverse
39           since this is forbidden by the second law of thermodynamics.
