12:00 am UTC - midnight UTC. See, what time is 12:00 am UTC (Coordinated Universal Time) in your local time. 12:00 am UTC - midnight UTC. Sunrises & Sunsets. UTC uses 24-hour (military) time notation and isbased on the local standard time on the 0° longitude meridianwhich runs through Greenwich, England. Midnight in Greenwichcorresponds to 00:00 UTC, noon corresponds to 12:00 UTC, and so on. UTC Conversion Table. Midnight is 00:00 so just subtract the timezone offset from midnight and that is what the UTC time will be when it's midnight in whatever timezone you started with – Dave Jul 7 '18 at 8:06 UTC is not a format, it's a time zone.

Local time is based on time zone and Coordinated Universal Time (UTC). UTC is commonly referred to as International Time, Universal Time (UT), Zulu Time(U.S. military), or Greenwich Mean Time (GMT). GMT was established by international conference in 1884 as International Time.
The earth is divided into 24 time zones, -11 to +12. Each time zone is 1 hour long, or 15° wide in longitude. Greenwich England is, by definition, in the middle of Time Zone 0, the prime meridian. UTC timeis the local time at Greenwich England. Time in other locations will be the UTC time hour plus or minus the local Time Zone. Daylight savings time adds 1 hour to the local standard (real) time.
Twenty four hour time does not use 'am' or 'pm', but courts hours from midnight (0 hours) to 11 pm (23 hours).AM / PM and 24 Hour Time

Daylight savings time (DST) is used in the summer months in some regions. DST is 1 hour ahead of standard time. There is no consistency between regions as to when DST takes affect, or reverts back to standard (real) time. DST was never practical and will eventually be phased out (obsolete).
- Atomic clock -- usually multiple clocks that count seconds (average of all clocks in system) based on the frequency of the cesium 133 atom (Cs) which oscillates at 9,192,631,770 Hertz.
- Mean solar time -- a measurement of the Earth's rotation with respect to the 'fictitious' mean sun.
- second -- One second (1 s or 1 sec.) is the duration of 9,192,631,770 periods of radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom (Cs).
- UT -- An abbreviation (for Universal Time) that should be used to show approximation of all the below.
- UT0 -- mean solar time on the Greenwich meridian obtained from direct astronomical observation. The time 00 hours being at Greenwich mean midnight.
- UT1 -- UT0 corrected for polar motion (widely used).
- UT2 -- UT1 corrected for seasonal variation in the Earth's rotation (a smoothed scale that does not reflect the real periodic variations in the Earth's angular position).
- UTC -- civil atomic time scale on or about the Greenwich meridian kept within 0.9 seconds of UT1.
Standard Date Format
Virtually the entire world formats time as Hours:Minutes:Seconds (hours listed before minutes, minutes listed before seconds). The date format Year-Month-Day has become widely accepted as a standard in many countries.
International Standard ISO 8601,
United States ANSI X3.30 and NIST FIPS 4-1,
Canadian standard CSA Z234.5,
European standard EN 28601,
British standard BS EN 28601.
The United States and many other countries use the Christian Gregorian calendar to mark years. This calendar has become a standard in such worldwide industries as aviation, and international commerce and trade -- however, other calendars do exist.
