I found 49:23 a while ago, which is the record, though it should be noted that this is the only improvement I have made to the escape timer. Basically all credit goes to Taco for optimizing the last few frames in Ceres.
Basically the "improvement" is that I fire a shot inside a door just before running through, which creates lag. Now the reason this improves the timer is that the timer can either move down by 00:02 or 00:01 per frame, and this is (as far as I know) decided not by the amount of ingame frames that have passed but how many frames in total (counting lag frames). Thus, by adding lag to the door I get a "clock pattern" that is 00:01 shorter while not actually being faster. And this can only be done in one room because the rest of the rooms already had the best patterns.
