From what I understand, time in territorial waters is governed by the country in question. Normally, that would be the time of the coastal region in that country, unless it has a specific law otherwise.
 
In international waters, your time zone is LMT to the nearest hour-offset (so -7½ to +7½ is UTC, -22½ to -7½ is one hour behind, and so on).

Subject: TimeZones and international waters

 

The maps of TimeZones that I have uncovered follow the country boundaries. 

 

Should the TimeZone Boundaries ideally follow international water boundaries?  i.e. If one is boating 10 Kilometers off the coast of Senegal, would the ship be on 0 standard time (like the country of Senegal with international water rights), or would the ship be on -1 standard time? 

 

Is there any regard with time zones for international water boundaries?

 

 

 

 

 

Let me know if I am not making myself clear!

 

Thanks for your assistance.

I'm forwarding this message from Joshua Kifer, who is not on the time zone mailing list. Those of you who are on the time zone mailing list should direct replies appropriately.

I finally found an implementation of this at CodePlex.  It's part of the PublicDomain project.

I hope this post adds some search fodder to the interweb for all those unlucky bastards seeking (and not finding) the same.
