How to export an absolute counter metric using the Count method?

My Go application uses a third-party package that exposes an internal metric cache_hits that gets incremented whenever a cache hits occurs.
It behaves as an ever growing int64.

Timestamp	Value
1	4
2	15
3	101
4	107

For timestamp 2, should I Count() the metric as its absolute value or as its delta from timestamp 1 ?

Count("cache_hits", 15, tags, 1) // absolute at 2

or

Count("cache_hits", 11, tags, 1) // delta from 1 to 2
