Again this is not that exact but it is the closest you will be able to get.
In my personal experiance I found that the Stamp gains 3sec over 1min. I guess this is not too bad but it definitly is not good. Over 15sec it doesn't gain too much so if you are trying to keep track of time in Autonomous mode then you should be ok.

That is correct, delta_t is the number of packets missed.
The loop speed is actually 26ms, not 25. If you use 25, you will be off by 2.4 seconds over a minute.
