 * TEST 1: TestExplodeImplodeTime
 * Description:
 * For each given timestamp T (a PRTime value), call PR_ExplodeTime
 * with GMT, US Pacific, and local time parameters.  Compare the
 * resulting calendar (exploded) time values with the expected
 * values.
 *
 * Note: the expected local time values depend on the local time
 * zone.  The local time values stored in this test are for the US
 * Pacific Time Zone.  If you are running this test in a different
 * time zone, you need to modify the values in the localt array.
 * An example is provided below.
 *
 * Call PR_ImplodeTime for each of the exploded values and compare
 * the resulting PRTime values with the original input.
 *
 * This test is run for the values of time T corresponding to the
 * following dates:
 * - 12/31/99 - before 2000
 * - 01/01/00 - after 2000
 * - Leap year - Feb 29, 2000
 * - March 1st, 2001 (after 1 year)
 * - March 1st, 2005 (after second leap year)
 * - 09/09/99 (used by some programs as an end of file marker)
 *
 * Call PR_Now, convert to calendar time using PR_ExplodeTime and
 * manually check the result for correctness. The time should match
 * the system clock.
 *
 * Tested functions: PR_Now, PR_ExplodeTime, PR_ImplodeTime,
 * PR_LocalTimeParameters, PR_GMTParameters.
