When the value of UNIFORM_LOG_TIMESTAMP_FORMAT is TRUE, the format used for timestamps in trace files is standardized on universal time with millisecond precision. For example: 

2012-09-26 00:16:47.154

When the value of UNIFORM_LOG_TIMESTAMP_FORMAT is FALSE, trace files include a mix of timestamps using different precisions, with some timestamps showing local time and other timestamps showing universal time.
