Some of zone records use 3 or 4 letter abbreviations that are tied to physical time zones, others use numeric UTC offsets. In Ireland , what Irish law designates as "standard time" is observed during the summer, with clocks turned one hour ahead of UTC.
Ephemeris time based on the standard adopted in 1952 was introduced into the Astronomical Ephemeris (UK) and the American Ephemeris and Nautical Almanac, replacing UT in the main ephemerides in the issues for 1960 and after. [30] (But the ephemerides in the Nautical Almanac, by then a separate publication for the use of navigators, continued to ...
Almost all government documents need to be filled up in the DD-MM-YYYY or DD/MM/YYYY format. An example of DD-MM-YYYY usage is the passport application form, [2] while the passport itself contains the date in DD/MM/YYYY format, [3] as does the PAN card (used for taxation purposes). But two expanded forms are used in India.
This is a list of the UTC time offsets, showing the difference in hours and minutes from Coordinated Universal Time (UTC), from the westernmost (−12:00) to the easternmost (+14:00).
Such designations can be ambiguous; for example, "CST" can mean China Standard Time (UTC+08:00), Cuba Standard Time (UTC−05:00), and (North American) Central Standard Time (UTC−06:00), and it is also a widely used variant of ACST (Australian Central Standard Time, UTC+9:30). Such designations predate both ISO 8601 and the internet era; in ...
The Indian Standard Time was adopted on 1 January 1906 during the British era with the phasing out of its precursor Madras Time (Railway Time), [2] and after Independence in 1947, the Union government established IST as the official time for the whole country, although Kolkata and Mumbai retained their own local time (known as Calcutta Time and Bombay Time) until 1948 and 1955, respectively.

A nakṣatra māsa, or astronomical month, consists of 30 days. Taking a day to be 24 hours, the smallest time unit, prāṇa, or one respiratory cycle, equals 4 seconds, a value consistent with the normal breathing frequency of 15 breaths/min used in modern medical research. [4]
[2] For any given date, the latest place on Earth where it would be valid is on Howland and Baker Islands, in the IDLW time zone (the Western Hemisphere side of the International Date Line). Therefore, the day ends AoE when it ends on Howland Island. [3] The convention originated in IEEE 802.16 balloting procedures. Many IEEE 802 ballot ...
