Casio Gulfman G9100 tide setting. where to find Lunar Tidal Interval?
If you look at the GMT differential in the manual, you'll notice that it corresponds to the offset from GMT that your time zone resides in. I live in San Antonio but i don't see that on the list. I do know that when we're not in Daylight savings time, I'm -6.0 from GMT... so that's what i set it for. Also, if you're near enough to the coast to use this feature, it would probably be a good idea to compare the watch reading to the actual tides and adjust accordingly.
Hope this helps.
