You asked on advice on the best practice. I would recomend you have the watch you use set to GMT and use only that time. The date and time for cel-nav is zulu so you can not go wrong.
I flew cargo planes all over the world and we only used zulu. When I would land one of the first questions was " what time is it? ". Never been a salior, but it seems to me that the deck time was local zone time, but for the use of the crew; when to eat lunch, when the six bells would ring, when to go to bed, etc. The master clock ( cronometer ) was showing zulu.
In this day and age to have a quartz watch set on zulu, date and time, would not be hard and if needed, wear a watch on local time.
Hope this helps.
