The fundamental reference point of the LV03 coordinate system was the old observatory of Bern, nowadays the location of the Institute of Exact Sciences of Bern University, in downtown Bern (Sidlerstrasse 5 - 46°57'3.9" N, 7°26'19.1" E). The coordinates of this reference point were arbitrarily fixed at 600'000 m E / 200'000 m N – with the ...
The two extreme time zones on Earth (both in the mid-Pacific) differ by 26 hours. Standard Time Zones, as of January 2, 2024 In the following list, only the rightmost indent of a group of locations is meant to indicate the area observing the offset; the places above and to the left are meant solely to indicate the area's parent administrative ...
The tz database partitions the world into regions where local clocks all show the same time. This map was made by combining version 2023d with OpenStreetMap data, using open source software. [1] This is a list of time zones from release 2025a of the tz database. [2]
In geodesy, geographic coordinate conversion is defined as translation among different coordinate formats or map projections all referenced to the same geodetic datum. [1] A geographic coordinate transformation is a translation among different geodetic datums. Both geographic coordinate conversion and transformation will be considered in this ...
The time of day always references the amount of time that has passed since midnight (standard time) in Biel, Switzerland, where Swatch's headquarters is located. For example, @248 BEATS indicates a time 248 .beats after midnight, or 248 ⁄ 1000 of a day (just over 5 hours and 57 minutes; or 5:57 AM UTC+1).
TT differs from Geocentric Coordinate Time (TCG) by a constant rate. Formally it is defined by the equation = +, where TT and TCG are linear counts of SI seconds in Terrestrial Time and Geocentric Coordinate Time respectively, is the constant difference in the rates of the two time scales, and is a constant to resolve the epochs (see below).
Geodetic coordinates are a type of curvilinear orthogonal coordinate system used in geodesy based on a reference ellipsoid. They include geodetic latitude (north/south) ϕ , longitude (east/west) λ , and ellipsoidal height h (also known as geodetic height [ 1 ] ).
