You're looking for DC_SAMPLE_RBT. This name has its roots in the Uwatec 
devices and means "Remaining Bottom Time". The Uwatec manual describes 
it as follows:

"Remaining Bottom Time, it is the time that a diver can spend at the 
current depth before having to ascend in order to reach the surface with 
the set tank reserve. The RBT accounts for all existing (if present) and 
upcoming decompression obligations."
