18# WARNING: this test changes the date of the system (and does not set it back).
19# This test sets the date of the current machine to $DATE1, creates a trace
20# makes sure the trace is really at that date, then restarts the trace, changes
21# the date to $DATE2, regenerates the metadata and validates that the trace is
22# actually at $DATE2.
