People search this because Temu puts a ticking clock on almost everything. The timers are real in the sense that they do something when they hit zero. They are not always real in the sense you assume, which is that the offer disappears forever.
Three different kinds of deadline
Wallet credits carry a genuine expiry date, visible in your coupon wallet, and when it passes the credit is gone. Session timers — the countdown on a cart or a banner — often reset when you return later, because their job is urgency rather than accounting. Public codes have their own validity windows that have nothing to do with the timer on your screen.
The 24-hour figure specifically usually refers to new-account welcome offers, which do frequently carry a short claim window. That one is worth treating as real.
How to check instead of guessing
Open your coupon wallet and read the date printed on the voucher. That is the authoritative answer for anything issued to your account. For public codes, use a source that states when it was last tested:

Do not let the clock decide
A countdown that pushes you into a purchase you were not planning has cost you money even if the discount was real. If the timer is the main reason you are buying, close the tab and see whether you still want the item tomorrow.
FAQ
Will my coupon come back if the timer runs out?
Session timers usually reset. Dated wallet credits do not come back once expired.
Is the new-user 24-hour window real?
Generally yes. Welcome offers often have short windows, so claim those early rather than saving them.
