I'm sure that said 24 hours until poll closes.
It closed (automatically) at exactly the time it was meant and set to close and I saw it, at various times, reporting it would close in "in X hours" "in X minutes", "in a few moments" and the logically iffy "a few moments ago". (I think I've got the wording correct, but it was a long time ago...).
As it happens, with a short duration poll (such as the 75-worders' 5 days), the software gives both the date and the exact time (i.e. May 31, 2020 at 12:59 AM). (Note that the format changes to "Tomorrow at 12:59 AM" when it's the day of closing
by GMT, but tomorrow
by BST.)
The poll one has to watch out for are the 300-worder ones: with a length of 15 days, the software does not initially report the time, only the date (which could give the unwary the idea that they have more time than they have, albeit only when the poll closes when daylight saving is in place, and only until the software starts reporting the time as well**). Note that
I (and other mods) can see both the time and date if I (we) use the poll edit mode, which is just as well, as it's best that I (not so much "we", as the other mods never get confused) don't get confused about what time I've (we've) set the poll to close.
All of the above relates to those of us in the UK and other places that may use (whatever they call) GMT
and daylight saving in the Northern hemisphere, i.e. Ireland, Portugal (other then the Azores), the Canary Islands, the Faroe Islands. (Many other countries use (their version of) GMT but not daylight saving, e.g. Iceland, Mauritania, Togo). I have no idea what the software is displaying elsewhere.
** - It seems -- I've just been checking -- that the time is displayed when there are about*** 10 days to go but not 11 hours.
*** - It depends on the number of hours, but my brain is too frazzled at the moment to check and, more importantly, as I'm not checking this around midnight GMT (during saylight saving), I may be getting a false impression of how the software is working out what to display and when. Perhaps the next time I'm around waiting for a poll to close, and have little else to do (
and I'm more than half-awake), I may re-open this investigation.
