Thanks for all the replies so far.
One of the reasons I have been asking for time is because my player was taking the time to bury her enemies, friends, taking 20 searching rooms, etc. I wanted to have a sense of realism, plus I always thought it would be cool to be able to have somewhat accurate time.
In regards to my player taking 20, according to the 3.5 rules, to search a 20 x 20 room would take roughly 30 minutes. During this adventure, there were no time constraints, but I want to get into the habit of keeping track of accurate time just in case there are. Plus, I think it would make some spells and abilities more meaningful, mainly the ones that last 1 minute per level.
Thanks everyone and more suggestions are still welcome.
