Its a hard grapple, I know. For me, the frustration level mounts daily...not good for an old fart with bad ticker

Something worth knowing:

1)Those SR/SS tables, both van's and IRL are in "LOCAL TIME". Its up to the mariner to compute UT (GMT).

2) Are we taking into account DayLight Time/DayLight Savings Time ?

3) I found out yesterday, while sailing NW in U.47 (AP 55° N, 7° 31' E), that the lower (white background) clock in SH3 dropped back one hour when the boat crossed meridian 7° 30' E, the boundary line between Prime Meridian 000° and 015° east.
edit: I'm going to replay this, just to make sure....
