I reference the U.S. eastern time zone, and so should everybody else.
Silly ethnocentric, don't you know that NYC (and the eastern seaboard along with it) is not the center of the world?
The International Time Bureau (BIH, "Bureau International de l'Heure") establishes and maintains Universal Time (UT) from which we derive the international time standard, Coordinated Universal Time ("Temps Universel Coordonné", UTC (so that neither the French nor the Americans could get their way -- "Fine! Neither of you can be happy!") ).
The time zone for UTC is Z (pronounced "Zulu") which has a UTC offset of zero (0). The US eastern time zone is R with offset of -5 and the US Pacific time zone is U with an offset of -8. When referencing UTC time, you give it as Zulu (eg, To convert from Z to U it's PST = Z - 8 and to convert from U to Z it's Z = PST + 8. Hence 0518U is 1300Z.
To my knowledge all US military message traffic keeps its timestamps in Zulu, thus eliminating ambiguity and the need for time zone conversions (an entire Navy course, NAVEDTRA 14252) in correlating reports.
The issue complicated by Daylight Savings Time (DST) in the US and Summer Time in Europe. When either is in effect (during a range of dates centering on the Northern Hemisphere's summer season), an hour is added to the local standard time (or two hours during "Double Summer Time"). Therefore, during DST the UTC offset for Pacific DS Time (PDT -- U+1) changes from -8 to -7 and for Eastern DS Time (EDT -- R+1) changes from -5 to -4. NOTE: DST never changes Zulu Time!
This year, DST went into effect on 13 Mar 2022 and Summer Time two weeks later on 27 Mar 2022. Therefore, both were in effect on 01 April 2022.
My own time stamp for Message 1 read "01-Apr-2022 5:46 PM", that being 1746 PDT (2022APR011746U -- I'm not sure how to indicate DST being in effect) which in reality was 0046Z of the next day (2022APR020046Z). You being stuck in the eastern time zone, your time stamp should read (assuming you use proper date format and not something weird like mm/dd/yy) "01-Apr-2022 8:46 PM", that being 2046 EDT of 01 Apr (2022APR012046R).
However, Tangle is in the UK, in Time Zone Z (UTC offset +0) but with Summer Time in effect which adds one hour to UTC giving him a local standard time of 0146. Thus the timestamp for your OP (Message 1) should read on Tangle's screen as 02-Apr-2022 1:46 AM (also note that dates in the UK are normal and not turned around).
Therefore, your OP was posted on 02 April for our members in the UK. QED
quote:Far out in the uncharted backwaters of the unfashionable end of the western spiral arm of the Galaxy lies a small unregarded yellow sun.
Orbiting this at a distance of roughly ninety-two million miles is an utterly insignificant little blue green planet whose ape-descended life forms are so amazingly primitive that they still think digital watches are a pretty neat idea.
This planet has - or rather had - a problem, which was this: most of the people on it were unhappy for pretty much of the time. Many solutions were suggested for this problem, but most of these were largely concerned with the movements of small green pieces of paper, which is odd because on the whole it wasn't the small green pieces of paper that were unhappy.
And so the problem remained; lots of the people were mean, and most of them were miserable, even the ones with digital watches.
Many were increasingly of the opinion that they'd all made a big mistake in coming down from the trees in the first place. And some said that even the trees had been a bad move, and that no one should ever have left the oceans.
And then, one Thursday, nearly two thousand years after one man had been nailed to a tree for saying how great it would be to be nice to people for a change, one girl sitting on her own in a small cafe in Rickmansworth suddenly realized what it was that had been going wrong all this time, and she finally knew how the world could be made a good and happy place. This time it was right, it would work, and no one would have to get nailed to anything.
Sadly, however, before she could get to a phone to tell anyone about it, a terribly stupid catastrophe occurred, and the idea was lost forever.
This is not her story.
