1100 Zulu (UTC) in US time zones
Military and aviation schedules give times in Zulu — Coordinated Universal Time — so that everyone works from one clock. When a message says 1100Z, this is the local time across the United States:
| Time zone | Standard time | Daylight time |
|---|---|---|
| Eastern (EST / EDT) | 6:00 AM — R | 7:00 AM — Q |
| Central (CST / CDT) | 5:00 AM — S | 6:00 AM — R |
| Mountain (MST / MDT) | 4:00 AM — T | 5:00 AM — S |
| Pacific (PST / PDT) | 3:00 AM — U | 4:00 AM — T |
| Alaska (AKST / AKDT) | 2:00 AM — V | 3:00 AM — U |
| Hawaii (HST) | 1:00 AM — W | No daylight time |
The letter after each time is that zone’s military time-zone letter: Eastern standard time is R (Romeo, UTC−5), so 1100Z is 0600R. Daylight time runs from the second Sunday in March to the first Sunday in November; Hawaii and most of Arizona stay on standard time all year.
