As a bash script rookie, detailed answers would be appreciated. :) I am trying to write a bash script that parses JPEG EXIF time stamps output from the exiv2 commmandline utility, which gives me typical output like: Image timestamp : 2010:07:27 17:38:52 Is there a way to parse the time stamp so that its components, like year, mont...

I have a 500K+ lines vb.net app, written by 10+ different devs over the past 5 years. Many times it gets the system time and/or date and relies on it. Now I have to re-run real cases thru the program for regression testing purposes, and it screws up cases where the date/time matter. My fix is easy, just replace all the areas in the pro...

Is there a way to get the time a piece of JavaScript actually runs on the CPU, like with the clock() and getrusage() functions in C? Using the normal Date() way only gives the wall time, and for performance measurements the CPU time would be much more useful. Note that I'm not looking for profiling tools, I want to reduce system noise f...
