test_droid will jump forward by two hours after the first log entry. The first time is the actual/correct local time, the second and subsequent lines are +2 hours. This +2 timestamp is applied to the line entries in all autoserv.* logs.
For example, here are the first few lines of test_droid execution/std[err,out]:
bryanlew@bryanlew0 files$ ./site_utils/test_droid.py whitelistedGtests
