Daylight Saving Time benefits retailing, sports, and other activities that exploit sunlight

Daylight Saving Time (DST)—also summer time in most countries including in British English and European official terminology (see Terminology)—is the practice of temporarily advancing clocks during the summertime so that afternoons have more daylight and mornings have less. Typically clocks are adjusted forward one hour near the start of spring and are adjusted backward in autumn.Modern DST was first proposed in 1895 by George Vernon Hudson.Many countries have used it since then; details vary by location and change occasionally.
The practice has been both praised and criticized.Adding daylight to afternoons benefits retailing, sports, and other activities that exploit sunlight after working hours,but causes problems for farming, evening entertainment and other occupations tied to the sun.Its effect on health and crime is less clear. Although an early goal of DST was to reduce evening usage of incandescent lighting, formerly a primary use of electricity,modern heating and cooling usage patterns differ greatly, and research about how DST currently affects energy use is limited or contradictory.
DST clock shifts present other challenges. They complicate timekeeping, and can disrupt meetings, travel, billing, recordkeeping, medical devices, heavy equipment,and sleep patterns.Software can often adjust computer clocks automatically, but this can be limited and error-prone, particularly when DST protocols are changed

Although not punctual in the modern sense, ancient civilizations adjusted daily schedules to the sun more flexibly than modern DST does, often dividing daylight into twelve hours regardless of day length, so that each daylight hour was longer during summer.For example, Roman water clocks had different scales for different months of the year: at Rome's latitude the third hour from sunrise, hora tertia, started by modern standards at 09:02 solar time and lasted 44 minutes at the winter solstice, but at the summer solstice it started at 06:58 and lasted 75 minutes.After ancient times, equal-length civil hours eventually supplanted unequal, so civil time no longer varies by season. Unequal hours are still used in a few traditional settings, such as some Mount Athos monasteriesand all Jewish ceremonies.

Ummm thx Google..I think
