Since Number Drop is still in beta testing, developers should adjust the amount of time provided each turn. Even playing on Slow Speed, time runs out—by the end of the game, both players have run out of time and are around -4:00. Happened every time I played, even though I understand the game and was moving at an anxiously fast speed.

You can create the table in training mode with no timer at all or if you use automatic, force this in the settings.

Well, that's not certainly the ideal solution... Fixing time limit is not that hard.
Sometimes the developer might set the timer too tight, thus making everybody go over time limit every time.
I experienced that in Hardback (and it was fixed quite fast). Post a report as a suggestion.

Edit: Seems to be a bug - https://boardgamearena.com/bug?id=50446

Seems to be a bug of timer not doing pluses actually
