How to Convert Time Converting  ZT In  our  previous  discussion  of  ZD,  we  said  that  each  standard  meridian to GMT (those meridians exactly divisible by 15) is 1 hour apart and that each of these  standard  meridians  is  identified  by  a  number  and  letter  sign.  To convert ZT to GMT, or GMT to ZT, the first thing you must determine is the  correct  ZD.  ZT  differs  from  GMT  by  the  ZD. Rule:  When  you  convert  ZT  to  GMT,  you  must  apply  the  ZD  to  your  ZT using the proper sign, minus (-) if you are in east longitude, plus (+) if in west longitude. Example  1:  Assume  that  you  are  in  longitude  105°E,  ZT  is  16h  23m  14s, and you want to find GMT. Step Action 1. Find  your  ZD.  105  ÷  15  =  7. 2. Determine  the  sign  of  the  correction.  You  are  in  east longitude, so the sign is negative. 3. Apply  the  correction.  Your  ZD  is  -7.  The  minus  sign means  that  you  subtract  ZD  from  ZT  to  obtain  GMT. ZT     16h     23m     14s ZD  -7 G M T   0 9 h   2 3 m   1 4 s Example  2:  Assume  you  are  in  longitude  75°W,  ZT  is  07h  13m  57s,  and you want to find GMT. Step 1. 2. 3. Action Find  your  ZD.  75  ÷  15  =  5.  Therefore,  you  are  in zone 5. Determine  the  sign  of  the  correction.  You  are  in  west longitude, so the sign is positive. Apply  the  correction.  Your  ZD  is  +5,  so  add  the correction to ZT to obtain GMT. ZT 7h 13m 57s +5 GMT  12h  13m  57s 5-11
