The time zones are in standard time, that is, excluding daylight time savings. By default, the corresponding local time zone is selected.

The new Vortex interface is designed to download all the calculations in any time zone.
GLOBAL TIME ZONES SOFTWARE
Some wind energy-related software even has a special feature to perform this test automatically. If the simulated data is available at different time zones, the best correlation between the observations and the model will always be for the matching time zone. Another way is by comparing the measurements against synthetic data. If the observations include temperature, a plot of the diurnal cycle of this variable can give a clue to the timestamp reference. In case the time zone at which some measurements were taken is ignored, there are several ways to find out. For the special case of weather observations, by convention they are taken in UTC, however, some sensors and data loggers can be configured to store the data in local time. Meteorological observationsĬomputers generally set the date and time file attributes to local time. Countries that previously used daylight saving time are colored in orange and countries that never used daylight savings are in red (Source: Wikipedia).
In the image on the left, the countries that observe daylight saving time are colored in blue. By definition UTC never adjusts for daylight saving time. It is sometimes referred to as winter time. Standard time is the local time of a country or region when Daylight Saving Time is not used. Time in LA = Time in NY – (UTC offset in NY) + (UTC in offset LA) = 23:59 – (-05:00) + (-08:00) = -20:59 Daylight Saving Timeĭaylight Saving Time (DST) is the practice of moving the clock forward one hour during summer so that sunset occurs at a later time, observed by some countries and sometimes only in certain regions of countries. UTC is also known as Zulu time or simply Z.Ĭonversion between time zones can be calculated by adding and subtracting the corresponding offset to UTC.
Since then, GMT is no longer a time standard but a time zone, although both share the same current time and are sometimes used incorrectly as synonyms. It is defined as the mean solar time at 0 degrees longitude. The Coordinated Universal Time or UTC was established in 1960 and it is the successor to Greenwich Mean Time.
GLOBAL TIME ZONES PORTABLE
The Royal Observatory established the Greenwich Mean Time (GMT), the solar time at that location (Greenwich, London) as a way of reference to sailors to calculate their current longitude, knowing the difference between the time onboard, which was the solar time at that location, and the Greenwich Mean Time kept by portable timekeepers. So when it is solar noon in Berlin which is 13.4 degrees east, it is about an hour before solar noon in London, located at the same latitude and 0 degrees of longitude. 15 degrees of longitude corresponds to 60 minutes of time. The apparent position of the Sun in the sky is different depending on the location due to the spherical shape of the Earth. As each time zone is 1 hour apart, we could expect that in the world there were 24 time zones, however, several time zones are separated by 30 and 45 minutes, so the total number of time zones is 40. Time zones around the world are defined by using positive or negative offsets, corresponding to moving east or west to the Greenwich meridian (longitude=0).
