Time zones give specific areas on the earth a time of day that is earlier or later than the neighboring time zones. This is because when it is day-time on one side of the earth, it is night-time on the other side. There are 24 time zones dividing the earth into different times, each with its own name, like the Indian Standard Time, Gulf Standard Time
Greenwich Mean Time (GMT) began in 1675. This was when the Royal Observatory at Greenwich was built to help ships find their longitude at sea. GMT was a standard reference for timekeeping when each city in England kept a different local time. By about 1900, almost all time on earth was in the form of standard time zones. Now, all places on earth are divided into time zones.
Greenwich Mean Time is now called UTC (Coordinated Universal Time). UTC is the time standard of the world. All other parts of the world are offset (plus or minus) according to their longitude. Most of the zones are offset by a full hour, but there are some offset by half an hour or 45 minutes.]]> 2017-05-18 14:50:28 UTC https://padlet.com/suchipanwar2/jhwxfma3mz0f/wish/172601351 https://padlet.com/suchipanwar2/jhwxfma3mz0f/wish/172903881 Time zones 
The world is divided into times zones ,each sprayed by 15 degree of longitude. The local time of a place depends on the meridian of longitude that passes through it. There are several longitude paying through India. 
The local time of the central Meridian of India, 82°30'E is taken as the standard Time for the entire country. It is called the Indian standard Time (IST). The central Meridian passes through Mirzapur near Allahabad. The standard Time of a country can be used to calculate how far it is ahead of behind Greenwich Mean Time (GMT).Greenwich mean time is the local time at Greenwich. Thus it can be used for the purpose of calculating time globally. GMT is known now as the universal time co-ordinated (UTC). since India is to the east of Greenwich. IST is five and a half hours ahead of GMT. Countries like Canada, USA and Russia with a vast longitudinal extent have more than one standard Time. Russia has 11 time zones-more than any other country!
International date line
The international date line is an internationally and time change line. It is drawn approximately along the 180°meridian. Deviating carefully to avoid land areas in the Pacific ocean. If one does this line while moving from West to east, you lose a day, and if one does this line while moving from east to west, you gain a day. For example , If it is 24juneto the west of the IDL, and 25June to the east of the IDL , now if you cross the IDL from West to east you will find that you have moved 24 to 25 June (you lose a day); and if you cross the IDL from east to west, you will find that you have moved from 25 to 24 June ( you gain a day ) .]]> 2017-05-20 05:46:06 UTC https://padlet.com/suchipanwar2/jhwxfma3mz0f/wish/172903881 https://padlet.com/suchipanwar2/jhwxfma3mz0f/wish/173388509 2017-05-23 13:44:02 UTC https://padlet.com/suchipanwar2/jhwxfma3mz0f/wish/173388509 https://padlet.com/suchipanwar2/jhwxfma3mz0f/wish/174272753 A time zone is a region of the globe that observes the uniform  standard time of legal, commercial and social purposes. Time zones lend to follow the boundaries of countries and the subdivisions  because it is convenient  for areas in close commercial or other communication  to keep the same time .Most of the time zones on land are offset from coordinated universal time by a whole number of hours , but a few zones are offset by 30 or 45 minutes (for example newfoundland standard time is UTC -03:30, Nepal standard time is UTC +05:45,and Indian standard time is UTC+05:30).Some  higher latitude and temperature zone countries use daylight saving time of part of the year, typically by adjusting local clock time by an hour, Many land time zones are skewed toward the west of the corresponding nautical time zones. This also creates a permanent daylight saving time effect.]]> 2017-05-29 16:14:45 UTC https://padlet.com/suchipanwar2/jhwxfma3mz0f/wish/174272753 jagathypillai https://padlet.com/suchipanwar2/jhwxfma3mz0f/wish/175054996 TIME ZONE
A time zone is a region of the globe that observes a uniform standard time for legal, commercial, and social purposes. Time zones tend to follow the boundaries of countries and their subdivisions because it is convenient for areas in close commercial or other communication to keep the same time.Most of the time zones on land are offset from Coordinated Universal Time (UTC) by a whole number of hours (UTC−12 to UTC+14), but a few zones are offset by 30 or 45 minutes (for example Newfoundland Standard Time is UTC−03:30, Nepal Standard Time is UTC+05:45, and Indian Standard Time is UTC+05:30). Some higher latitude and temperate zone countries use daylight saving time for part of the year, typically by adjusting local clock time by an hour. Many land time zones are skewed toward the west of the corresponding nautical time zones. This also creates a permanent daylight saving time effect.]]> 2017-06-03 09:31:50 UTC https://padlet.com/suchipanwar2/jhwxfma3mz0f/wish/175054996
