The crossing of the 180 ̊ prime meridians can result in the change of time zone. Thus some precautions have to be taken to avoid the confusions in the time zones. Thus the date and time may have to be changed to incorporate this. This has to be made by considering the Greenwich 180 ̊ prime meridian. When we travelling across the meridian, the day and the date changes. While travelling from east to west, one day has to be added to the day of commencing the journey. But while travelling from west to east, the same day is considered upon arrival.
