    Time Zones

    AMy 2102-D Modification (Navlist 9522)  (?YACHTSMAN? was made to teach CELO 
    NAVIGATION. The outer rim of the Base Disk can teach ?TIME ZONES? It gives a 
    bird eye view of the earth with the  24 hour TIME, allowing the student to 
    see the TIME ZONE system and how it works.
    I think that NAVLIST, may be interested in this way of thinking.
    Below is a time Zone chart. It can change your time From Local Mean Time( 
    LMT), Your clock, your wristwatch to Greenwich Mean Time (LMT) and back to 
    your Local. Longitude time or any other LMT on this earth. 
    1. Find your LONGITUDE, on the outer rim.
    2. See your TIME within 7.5 degrees of your LONG. (00-12-00.
    3. Find the difference to your time and GMT at 12:00 this is ZD.
    4. Add ZD in the west Hemisphere, Subtract in the EAST.
    5. This is GMT,{ from your LMT to GMT.} (Use the difference).
    6. To get back to your LMT reverse the sign. ? ? ?. 
     7. When at GMT on the outer rim,, to find the time at another LONG, Read time 
    at that LONG, once again Find the difference from 12:00 to the new LONG. 
    Time, reverse the sign and add or substract.
    Example: Your are at 73W, read 17:00. so your Zone description from 12:00 is 
    +5. Your LMT clock reads 10:05, GMT is 10:05 (+) +5=1505GMT, You want to find 
    the LMT at 72E. You read the time as 6:00, your zone description is 12:00 to 
    6:00,  a  -5. You reverse the sign and add,. LMT at 72E is 15:05 GMT +5 
    =20:05 .
