Comments on Tables

The UNKNOWN time is caused by data gaps due to Safehold as follows:

76.642 minutes detected at 2006-01-01 11:23:13.00
75.006 minutes detected at 2006-01-01 12:57:33.00
72.9087 minutes detected at 2006-01-01 14:32:09.00
71.2688 minutes detected at 2006-01-01 16:06:44.59
72.5772 minutes detected at 2006-01-04 21:20:39.00
56.6615 minutes detected at 2006-01-04 22:38:38.43

These impact on not only the detected gaps, but force the 'unknown' condition on the data immediately following.
