Remaining time display > 24h

Just a minor observation:

I rendered a project of about 1h length, and I used best possible quality, which made rendering time long.

I realized that the display of the remaining time obviously sets in only after the calculated remaining time is below 24h.

Has anyone experienced that too?

The remaining time is not computed until after a few % increase because it uses the time between increments to compute an estimate. If your export will take many hours, it will take a long time to get an estimate as you experienced.
