In the Northeast, the sun rises as early as four in the morning and in winter it sets by four in the evening. By the time government offices or educational institutions open, many daylight hours are already lost. In winter this problem gets even more accentuated and the ecological costs are a disaster with much more electricity having to be consumed.
Studies claim that advancing IST by half an hour would result in saving 2.7 billion units of electricity every year. None of the other proposals such as the introduction of daylight saving time in India has met with any approval and it is felt that having two time zones would be unsuitable.
There is of course a strong political dimension to granting a separate time zone in the Northeast given the region’s long history of self-determination movements.
The unstated assumption is that the grant of a different time zone is only the first temporal step towards conceding spatial autonomy. This appears to me to be a short-sighted perspective.
If socioeconomic development is indeed one of the formulae to combat insurgency, might it not be worthwhile to consider the disastrous impact that IST has on productivity and efficiency in the region?
On the other hand the United States uses nine standard time zones. From east to west they are Atlantic Standard Time (AST), Eastern Standard Time (EST), Central Standard Time (CST), Mountain Standard Time (MST), Pacific Standard Time (PST), Alaskan Standard Time (AKST), Hawaii-Aleutian Standard Time (HST), Samoa standard time (UTC-11) and Chamorro Standard Time (UTC+10). View the standard time zone boundaries.
Daylight Saving Time begins at 2:00 a.m. local time on the second Sunday in March. On the first Sunday in November areas on Daylight Saving Time return to Standard Time at 2:00 a.m. The names in each time zone change along with Daylight Saving Time.
Eastern Standard Time (EST) becomes Eastern Daylight Time (EDT), and so forth. Arizona, Puerto Rico, Hawaii, U.S. Virgin Islands and American Samoa do not observe Daylight Saving Time. Read more about the new federal law that took effect in March 2007 which extended daylight saving time by 4 weeks.
