While the former indicates that a date and time value is Coordinated Universal Time (UTC) by assigning DateTimeKind.Utc to its Kind property, the latter assigns the date and time value the UTC time's offset (equal to TimeSpan.Zero). UTC’s second is far more precise than GMT's original second. In 1972 leap seconds were introduced to synchronize UTC time with solar time. These 2 turning points (different definition of a second and the introduction of leap seconds) ‘forced’ GMT to be the same as UTC based on what seemed a gradual, tacit convention. Time Changes in UTC Over the Years Daylight Saving Time (DST) changes do not necessarily occur on the same date every year. Time zone changes for: Recent/upcoming years 2020 — 2029 2010 — 2019 2000 — 2009 1990 — 1999 1980 — 1989 1970 — 1979 1960 — 1969 1950 — 1959 1925 — 1949 1900 — 1924 1850 — 1899 1800 — 1849.
From LongJump Support Wiki
UTC is a standard date and time format.
Dates
A date in UTC format looks like this:
- 2010-11-12
That format contains a four-digit year, a 2-digit month, and a 2-digit day, separated by hyphens (yyyy-MM-dd).
Times
A time in UTC format looks like this:
- 13:14:15Z
That format contains 2-digits for the hour (13), based on a 24-hour clock, followed by two digits for minutes (14), and two digits for seconds (15), separated by colons (HH:mm:ss).

- Although the standard allows for milliseconds, the platform does not use them or accept them.
- The final character in the format designates the time zone, where Z is 'zero-time', or Greenwich Mean Time.
- Times should be expressed with the UTC designator ‘Z’. It should not be expressed using a timezone offset.
Date/Times
A date/time looks like this:
- 2010-11-12T13:14:15Z
That format contains a date and a time, separated by the letter 'T'.

Current Local Time In (UTC/GMT)
Brian lives in Australia and needs to convert a UTC time into his local time. Problem is, he doesn't know how to go about doing it.
Utc Time
UTC is an abbreviation for Coordinated Universal Time. (Yes, I know it looks like the abbreviation letters are out of order. They are; this is why it isn't an acronym. The abbreviation is—believe it or not—based on a political compromise.) UTC is equivalent to International Atomic Time with leap seconds added at irregular intervals to compensate for the Earth's slowing rotation. UTC is never out of synch with GMT (Greenwich Meridian Time) by more than nine tenths of a second, so the two (UTC and GMT) are virtually equivalent in common usage.
Because of this, all you need to do to convert from UTC to a local time is to figure out how many hours your time varies from GMT. There are any number of Websites you can visit to determine such information; the following is an example of one you can use. (Just click a city near you that you know is on the same time zone as you, then look at the resulting time to see how many hours different you are from GMT.)
If you are near Sydney, Australia, you can see that your local time is ten hours ahead of GMT. This means that to determine the local time if you know UTC, all you need to do is add ten hours to that time. If the UTC is in cell B3 in Excel's date and time format, then you could use either of these formulas:
You should understand that these formulas don't account of Daylight Savings Time. If you live in an area that implements some sort of time adjustment scheme (such as DST), then you will need to adjust your formulas accordingly. This means that if you are near Sydney you need to figure out when DST starts and ends, and if you are currently affected by DST you will need to add eleven hours to your UTC value.
