Time is short
Looking for a tidy word or phrase for the sense of time is short, as in sunseting an item, expiring due to time allowed, or a certification is lapsing.
Thanks.
Down to the short strokes
Down to the wire
Tick, tick, tick.
Don't blink.
Slip sliding away.
Closing time.
"Hurry up, please, it's time."
The echo of opportunity's knock.
Circling the drain.
... or forever hold your peace.
Time's a-wastin'
It's later than you think
[Something is] moribund
On a short deadline
In a time crunch
Window of opportunity
Life is short
Act now
Don't delay
Last chance
Urgent
On short notice
A rush job
I haven't got all day
