The 24-hour clock (Z-time) begins at midnight (00Z) at this prime meridian. 00Z for the United States begins in the evening local time. Z-time does not change with the change for daylight saving time but the local time will change.
When you see 12 UTC or 1200 UTC or 12Z (all are the same and depend on forecaster preference), it refers to noon at Greenwich. 00 UTC or 00Z is midnight Greenwich time.
Think of Z like you would if you saw "GMT" or "UTC." "Z" time is short for "Zulu" time from the NATO Phonetic Alphabet, and is set to the same time as global time standard "UTC" (Universal Time, Coordinated) -- which is the same time as the old Greenwich Mean Time, or GMT (Got all that?)
12Z is 1200 hours, or 12 p.m. (noon), local standard time in Greenwich, while 18Z is 1800 hours, or 6 p.m., local standard time in Greenwich.
UTC is an international 24 hour time and date standard (Coordinated Universal Time), which is the same as GMT (Greenwich Mean Time). The UTC times are displayed on all radar images above the legend. Local times are shown above the radar controls in the looping interface and underneath the legend for single images only.
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.
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). Adjust for daylight saving time. UTC time is not adjusted to reflect daylight-saving time.
The 24-hour clock (Z-time) begins at midnight (00Z) at this prime meridian.
The letter (Z) is the symbol used to represent integers. An integer can be 0, a positive number to infinity, or a negative number to negative infinity.
Ż, ż (Z with overdot) is a letter, consisting of the letter Z of the ISO basic Latin alphabet and an overdot. This article contains phonetic transcriptions in the International Phonetic Alphabet (IPA).
To make your clock run faster, move the lever to F (or +, or "Faster"). To make it run slower, move the lever to S (or -, or "Slower"). Move the lever in small amounts at a time, and move it slowly. A movement of the lever by only 1/8" should make your clock run 5 minutes faster or slower.
Models listed as a 0z or 12z run mean that is the time they were initialized. It typically takes considerable time (especially for global models) for the actual output to arrive after the initialization time.
Since Greenwich is the site of the “zero meridian,” they called GMT “Zero Time” or simply “Z- Time.” In the phonetic alphabet that the flyers of the time used to make themselves understood on their radios, “Z” became “Zebra.” When the alphabet was changed, the call sign became “Zulu.”
Military Time 2200 is: 10:00 PM using 12-hour clock notation, 22:00 using 24-hour clock notation.
Zulu comes from the US military, which assigns global time zones with letter codes. The UTC time zone carries the letter Z, which in the phonetic alphabet is expressed as “Zulu.” And saying Zulu will make you sound more like a fighter pilot.
. 000 is the fraction of a second and Z indicates UTC timezone. How you convert to your local time will depend on which programming language you prefer, but for example Perl has standard modules for parsing and formatting times.
An offset of zero, in addition to having the special representation "Z", can also be stated numerically as "+00:00", "+0000", or "+00".
A timestamp in Zulu format would look like TZ. That is a date “YYYY-MM-DD” with the four-digit Year, two-digit month and two-digit day, “T” for “time,” followed by a time formatted as “HH:MM:SS” with hours, minutes and seconds, all followed with a “Z” to denote that it is Zulu format.
Countries with a large distance from west to east are often devided into two or more timezones to adjust daytimes to the position of the sun. Timezones are always computed relative to UTC, the "Universal Time Coordinated".
When “Z” (Zulu) is tacked on the end of a time, it indicates that that time is UTC, so really the literal Z is part of the time. What is T between date and time? The T is just a literal to separate the date from the time, and the Z means “zero hour offset” also known as “Zulu time” (UTC).
