Winter Time

Standard time

Standard time is the synchronisation of clocks within a geographical region to a single time standard, rather than a local mean time standard. The term is also used to contrast with daylight saving time, a period of the year when clocks are shifted ahead one hour, supposedly to make better use of daily sunlight from spring to fall. Applied globally in the 20th century, the geographical regions became time zones. The standard time in each time zone has come to be defined as an offset from Universal Time. A further offset is applied for part of the year in regions with daylight saving time. Generally, standard time agrees with the local mean time at some meridian that passes through the region, often near the centre of the region. Historically, standard time was established during the 19th century to aid weather forecasting and train travel.

Winter time (clock lag)

Winter time is the practice of shifting the clock behind standard time during winter months, usually −1 hour. It is the opposite of daylight saving time in that the different time is in effect during winter months, rather than the usual case where the different time is in effect during summer months. However, while summer time is widely applied, use of winter time has been and is very rare.

Winter

Winter is the coldest and darkest season of the year in temperate and polar climates. It occurs after autumn and before spring, when the hemisphere is oriented away from the Sun as a result of the tilt of Earth's axis. Different cultures define different dates as the start of winter, and some use a definition based on weather.

Time

Time is the continuous progression of existence that occurs in an apparently irreversible succession from the past, through the present, and into the future. Time dictates all forms of action, age, and causality, being a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in conscious experience. Time is often referred to as the fourth dimension and the temporal dimension, in addition to the three spatial dimensions.
