UTC time is 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. The best time to call from EST to UTC. When planning a call between EST and UTC, you need to consider time difference between these time zones. EST is 5 hours behind of UTC. If you are in EST, the most convenient time to accommodate all parties is between 9:00 am and 1:00 pm for a conference call or meeting. In UTC, this will be a usual working time of between 2:00 pm and 6:00 pm. NIST Time Widget. This widget is a public service provided by the Time and Frequency Divisionof the National Institute of Standards and Technology (NIST). It is a web clock showing the official time of day from NIST, displayed as a 12 or 24-hour clock, in a user-selectable time zone. The time reference for the widget is the output of the national time scale called UTC(NIST), which disseminates Coordinated Universal Time UTC.

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).

Time In Utc 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).

DEFINITIONS
  • 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.

Year Month Day

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.

Year 2000
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. Fredro starr and brandy.

INTRODUCTION

Microsoft uses Coordinated Universal Time (UTC) format, an international standard 24-hour timekeeping system, to document the created dates and times of files that are included in a software update. This article describes how to convert UTC to local time to verify that the file that is on your computer is the one that is discussed in the documentation.

More Information

To convert UTC to local time, follow these steps:

  1. Determine your local time offset from UTC time. To do this, follow these steps on a Microsoft Windows-based computer:

    1. Click Start, click Run, type timedate.cpl, and then click OK.

    2. Click the Time Zone tab, and then verify that your local time zone is selected. If your local time zone is not selected, click it in the list of available time zones.
      The local time offset is shown at the start of each local region list item. For example, -5:00 is the local time offset for Eastern Time (US & Canada):

      (GMT-5:00) Eastern Time (US & Canada)

  2. Add the local time offset to the UTC time.
    For example, if your local time offset is -5:00, and if the UTC time is shown as 11:00, add -5 to 11. The time setting when adjusted for offset is 06:00 (6:00 A.M.).
    Note The date also follows UTC format. For example, if your local time offset is -8:00, and if the file's UTC time is shown as 00:00 (12:00 midnight) on Monday, the adjusted time is 16:00 on Sunday (4:00 P.M., Sunday).

  3. Adjust for daylight saving time.
    UTC time is not adjusted to reflect daylight-saving time. If your time zone participates in daylight saving time, add the time difference to the file's offset-adjusted time when daylight saving time is in effect. For example, if daylight saving time in your time zone is one hour ahead of standard time, add one hour to the offset-adjusted time.

  4. Convert the 24-hour time format to 12-hour time format if your local time uses the 12-hour format. To make the conversion, follow these steps:

    • If the offset-adjusted time is between 12:01 and 23:59, inclusive, subtract 12 from the adjusted time, and then append P.M.

    • If the adjusted time is between 00:01 and 11:59, inclusive, leave the adjusted time as is, and then append A.M.

    • If the adjusted time is 00:00, use 12:00 midnight.

    • If the adjusted time is 12:00, use 12:00 noon.

Notes

Time In Utc 24 Hour Chart

  • You can use this method to compare the file's converted time to the time of a software update file that is on your computer.

  • When you view the file details of the file that is on your computer, the date in the Date Modified column may be different from the date in the Date Created column. If this difference occurs, use the date in the Date Modified column.
