Answer posted after another was accepted, but I think a good alternative could be
The Beginning of Time.
I think it's:
Time is up: The period of time allowed for something is ended.
Because:
The arrow is pointing up where time is. So time is up [there].
It could be
Tea time (T + time)

It could be
High time, as in "It's high time someone solved this puzzle".
Or it could be
Uptime, as in the amount of time a server has been running.
It could be
Tea time
Since
the arrow is pointing to the letter "t" opposed to the whole word it may be suggesting the word tea.
It can be
Time arrow. As scientist usually use, to explain the beginning and end of time.
