Depends on the size of the glyph needed and how many, but in a case of a single nevermore the size Ruby and them faces=d, it would last for maybe a few seconds to a couple mins (3-5 at most). As for time dilation 10 second normal time would be like .01 seconds to the effected or whatever it'd take to make it look like a bullet has stopped in place.
