Aaaaaaaaaaaaaaaaand... i'm back (awake): yes, it can be done, and for a "simple" logical reason: you can change the time manually already; and it sticks. iow one could write some script that does this automatically...
That said: my approach would be to check 'what writes to this value ?'. And I'm pretty sure some multiplier will be applied prior to writing/updating that time_value. (or you can insert one there and then)
=> find that multiplier, change it manually and see what happens...
anyways: I have a quick look this evening, and report back...
