Subtract the values from the first snap from their corresponding values in the second snap, and you'll have statistics info for the duration of the window.

(Note that unlike latch numbers, the statistics numbers are invariant across Oracle versions, so, I know that 12 is CPU used by this session, regardless of what version you're on.) Only V$SYSSTAT has the NAME column built in, so if you're using V$SESSTAT or V$MYSTAT, you'll have to join to V$STATNAME.
