Description:

This is a PHISH library function which can be called from a minnow application. In PHISH lingo, a "minnow" is a stand-alone application which makes calls to the PHISH library.

This function provides a portable means to time operations within a minnow. The function returns the current wallclock time as a timestamp measured in seconds. To calculate an elapsed time, you need to bracket a section of code with 2 calls to phish_timer() and compute the difference between the 2 returned times, as in the example above.
