Penang Lunitidal Setting
I was setting the lunitidal value for my new casio watch so that it would tell the moon and tidal phase accurately. I found it very hard to find the settings on the net so I shall share it here.
Time zone +8
Latitude 100 degrees east
Lunitidal interval +1

Hi Doc.
I just bought new Casio G-Shock Gulfman with tide graph.
Just want to ask something about Lunidital Interval setting.
U post in ur blog that for Penang we must enter +1 for interval time.
Does that mean +1 equal to 1:00?
Thanks.
Hi! Yes +1 does mean 1.00 in the Interval Setting.
Thank you very much Doc.
Thanks a bunch doc!I've been looking for the lunitidal interval for ages!malaysia doesn't seem to release this sorta thing online.
Your welcome, had to figure it out myself. Anyway sometimes you may have to tweak it a little by observing the actual tides in your area.
Hi
Also just bought a Gulfman and cannot find the settings for Dubai, any idea where i can?
Hi Doc, is it Penang Lunidital Interval is same in Kuala Lumpur? Just bought a guflman :) Thanks.
Hello to all Lunitidal Interval seekers, i have a Gulfman myself and after much searching, and figuring it out like most of you out there do, i manage to somehow lock down the Lunitidal Interval setting for Kuala Lumpur. The closest coast for me to say would be Port Klang, hence the calculation below:
Long.: 102 degree East
Int.:6:30
After you key in the number, you can somehow cross reference it with the tidal forecast website below:

For your knowledge, the local Lunitidal interval can be calculated using :
Lunitidal Interval = Greenwich Interval - (0.069 * L) -----> negative value
By adding 12.42 to the answer above will give a positive local lunitidal value
where L=longitude for the location in degree (West longitudes are positive ; East longitudes are negative)
For our region (Peninsular Malaysia), we use +8 as our Greenwich interval,thus :
location: N 3°8' E 101°42' = N 3.13333° E 101.7°
Lunitidal interval for the above mentioned location can be derived by :
Lunitidal interval = +8 - [0.069 * (- 101.7)] = 15.0173 hour = 15:01

well the formula is right but little ammendment 8--7=15 the less the gmt (8) so the anwser is 7
