What

A port of John Trupiano's awesome Timecop Ruby to Javascript.

Call Timecop.install() once to get started. This replaces Date with Timecop.MockDate. After that, you can travel through time at will.

Travel to the morning of October 17, 2010, and allow time to continue advancing:

Timecop.travel(new Date(2010, 10, 17, 11, 45));

Travel to the afternoon of January 21, 2012, and keep time frozen then:

Timecop.freeze(new Date(2012, 1, 21, 14, 30));

Return to the present:

Timecop.returnToPresent();

Finally, to uninstall Timecop and reinstate the native Date constructor:

Timecop.uninstall();
