Get time difference since a time stamp

Compute the time difference between a high speed time stamp and current time.

Usage

get_seconds_time_delta_since(then)

get_nano_time_delta_since(then)

get_micro_time_delta_since(then)

get_milli_time_delta_since(then)

Arguments

then

HighResTimeStamp defined in OmniDriver API and retrieved or constructed with other OmniDriver API methods. Not vectorized!

Value

a numeric vector of length one giving the time difference in seconds, milliseconds, microseconds or nanoseconds.

Note

Nanosecond timing and normal timing are not coincident, but as both are stored in parallel, the differences should differ only in their resolution.
