Time zones simply create a workable 'day' and 'night'. If countries didn't use time zones (and the whole planet worked on the same time), people would be going to bed at (for example) 9am just because it was dark then. Time zones bring sensibility to daily life. The only disadvantage - is having to adjust to different times when you travel overseas. For example - it might be 8am when you depart, but (after travelling through a number of time zones) - it might only be 2am local time.

Some are off by 15 minutes such as Nepal. In the Pacific several islands have their own time zones. They will share the same time as a neighboring island, but they are one calendar day ahead or behind their neighbors.

There are several calendars in use presently. Time Zones are calculated from The Prime Meridian, no matter which calendar is in use. All international business and commerce uses the Gregorian calendar. For religious and spiritual dates in calendars other than Gregorian local time is used so time zones are not a concern.
