![]() ![]() Since we need to account for daylight savings in some cities, we’ll also add a column for that, as well as the final offset from UTC. When you add contacts to your employees list, you’d also like to add their home office and local time.įirst, we’ll set up a table of locations that includes the city, time zone, and the offset from UTC, not including daylight savings time. For a greater level of specificity, you can use the Now button to populate your page with the current time. TimeZone Fix Allows you to convert (date and time) across time zones on the pages you visit. ![]() Let’s say your company has offices in six locations. A time zone converter that simply requires right-clicking and highlighting to make the change. Pacific Standard Time (PST) is eight hours behind UTC, so you would use the formula:Ĭentral European Time (CET) is one hour ahead of UTC, so you would use the formula: Returns the date and time in offset time zone. To convert UTC to a different time zone, we can use the NOW() function to subtract/add the offset to UTC and divide by 24. In Honeycode, all dates and times are in UTC, which may require a simple conversion to set up notifications in your local time zone. In fact, removing the letters from their numeric meaning might serve to make it easier to code and decode the ammZ times.Coordinated Universal Time (UTC) is the primary standard for regulating clocks and time around the world. Instead, I see that "S" lies at the 3PM slot on the Zone Delta conversion slot, meaning that if it's 3PM local time for me, I can report that time as S00Z. For example, when I'm under Canadian Atlantic Standard Time (UTC-4), I don't really care that "S" is valued at "19". Since we're generally not very interested in solar times in Greenwich England, it's not actually necessary to consider the actual values for the single letter codes for the hours. In the system presented here, local midnight (and the negative offset from Z) for each zone is the same as the zone's letter designator. I thought using A-W to represent 01-23 was a bit more natural. Nautical time does something similar with the zones. His original proposal for universal time included letter-coded hours, but omitting "I" and "U". The idea for the conversion charts came from reading the book Time Lord (2000), by Clark Blaise, a biography of time zones pioneer of Sandford Fleming. So if he's using Zone Alfa he will have to add 30 minutes before he reports his Zulu time. Similarly, he could use Zone Alfa, but his own time is 30 minutes behind that. Therefore, he will have to subtract 30 minutes from his clock time before he reports his Zulu time. If Bob is reporting times in this zone, he can use Zone Charlie, but his own time is 30 minutes ahead of this. For example, Canadian Newfoundland Daylight Time is UTC-02:30. Some time zones have offsets from UTC that are not whole hours. Note on time zones with part hour offsets She could then use a short time stamp like 12/14 D10Z or 12/14 0410Z to report the "Zulu" time. Since on the chart she is after time "Z" and before her local midnight, she adds one day, making it December 14th. It's 8:10PM, so she examines the chart, finding that the 8 O'Clock spot on the PM (outer) ring reads "D", so her ammZ code for the present time is D10Z, or 04:10 UTC. Alice sees that she's under US Pacific Standard Time, which is UTC-08:00, so she brings up the conversion chart for Zone Hotel. ![]() Suppose Alice is at the University of Washington at Seattle, WA, (where foldit is based) and it's December 13th. Note that for the purposes of table lookup UTC+13:00 is the same as UTC-11:00, UTC-14:00 is the same as UTC+10:00, and so on. If it's afternoon and the analog "little hand" is pointing as it would for 4PM and the little hand is pointing as it would for 35 minutes past the hour, the ammZ code would be P35Z, 16:35 UTC and so on.įolders in time zones with exact hour offsets from UTC can find their offset and load their proper conversion chart from the following table:Ĭonversion chart by time zone - UTC offset For example, if the hands show midnight, that's Z00Z, which is equivalent to 0000Z, 00:00 UTC, 12AM Z, 12AM Zulu and so on. Should you be looking at the hands of an analog clock set to Coordinated Universal Time (UTC), a four character "Zulu" time ammZ can be directly read from the chart. , W) placed on an analog clock face with the AM letters in an inner ring, the PM letters in an outer ring. The Zone Zulu chart has the 24 single letter hour aliases (Z, A, B. The letters will sometimes be expanded to their equivalent Nato Phonetic Alphabet telephony codes: Zulu, Alfa, Bravo, Charlie. ![]() , 22, 23 we will use 24 letters as follows: Z, A, B, C. Besides the twenty-four hour clock hours 00, 01. The charts are be based on Hour Aliases, a series of aliases (synonyms) for the twenty four hours 12AM, 1AM.
