Halfway through an overnight shift the clock stops being a measure of the day and becomes a measure of what is left of the night. If 11:48 pm is the next break, the handover, or the point somebody relieves you, this page holds the exact gap and refreshes it every second on its own.
Nothing here is stored, sent or remembered. The page works out one number from your device's clock and draws it, and that is the whole of what it does. Closing the tab leaves nothing behind, and there is no history of times you have looked up sitting anywhere afterwards.
Plenty of phones and dashboards default to a 24-hour display regardless of how people around them actually speak, so 23:48 may well be the figure staring back at you while 11:48 pm is what anyone would say out loud. Neither form is more correct; they are just aimed at different readers.
Common questions
Do the clocks change here?
No. The UAE has no daylight saving at all, so the offset stays at UTC+4 in every month. When the gap to Europe or North America shifts, it is their clocks that moved, not yours.
What is 23:48 on a 12-hour clock?
The same instant is 11:48 pm in writing and twelve minutes to twelve at night out loud. Anything from 13:00 onwards loses twelve to give the pm figure, which is the only sum involved in moving between the two.
Does the number update by itself?
Yes. It is recalculated every second from your device's clock, so nothing needs refreshing or restarting. Whatever is on screen is the current gap to 11:48 pm, not a figure worked out when the page first opened.
What happens once 11:48 pm has passed for today?
The count rolls over and carries on towards the same time tomorrow. That happens on its own at the moment the time passes — the page does not need reloading and there is nothing to reset by hand.
