Subject: Re: [htdig-dev] Feature: Execution time

According to Jim Cole:

That's easy enough...

This patch shows the effective execution time of an htsearch query,
in seconds.

Tue Aug 13 11:44:01 CEST 2002 Gabriele Bartolini <angusgb@users.sourceforge.net>

	* htsearch/Display.[h,cc]: added execution time feature (EXECUTIONTIME
	template variable)
	* htsearch/htsearch.cc: calculates the execution time through
	'gettimeofday'
