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). It includes countries and regions that observe them during standard time or year-round.
It was determined as 5 hours, 53 minutes and 20 seconds ahead of Greenwich Mean Time (UTC+5:53:20). Calcutta Time was described as being 23 minutes and 20 second ahead of Indian standard time and one hour, two minutes and 20 seconds ahead of Bombay Time. [1] It has also been described as 32 minutes and 6 seconds ahead of Madras Time (UTC+5:21: ...
In 1802 Madras Time was set up by John Goldingham [7] and this was later used widely by the railways in India. [8] Local time zones were also set up in the important cities of Bombay and Calcutta and as Madras time was intermediate to these, it was one of the early contenders for an Indian standard time zone.
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 ...
As many decimal places may be used as required for precision, so 0.5 d = 0.500000 d. Fractional days are often calculated in UTC or TT, although Julian Dates use pre-1925 astronomical date/time (each date began at noon = ".0") and Microsoft Excel uses the local time zone of the computer. Using fractional days reduces the number of units in time ...
Software timekeeping systems vary widely in the resolution of time measurement; some systems may use time units as large as a day, while others may use nanoseconds.For example, for an epoch date of midnight UTC (00:00) on 1 January 1900, and a time unit of a second, the time of the midnight (24:00) between 1 January 1900 and 2 January 1900 is represented by the number 86400, the number of ...
The time is calculated based on the offset from UTC for the specified timezone taking into account whether daylight saving time is currently active in that timezone. The offset for each implemented timezone is calculated in a sub template (except for UTC).
It was then decided that India would have two time zones, Calcutta (now Kolkata), and Bombay (now Mumbai). Bombay Time was set at 4 hours and 51 minutes ahead of Greenwich Mean Time (GMT). [1] [2] However, Bombay Time was difficult to convert to Indian Standard Time (IST) after it was adopted on 1 January 1906 as the official time zone of India.
