cbmem: export base_time in timestamp table

It's helpful to know the base_time (1st timestamp) in the
timestamp table because it provides more information like
the accumulated time before the first timestamp was recorded.

In order to maximize this information report the base time
as an entry that is printed. It's called '1st timestamp'.
The implementation turns all the timestamp entries into absolute
times so one can observe both absolute and relative time for
each marker.
