subtracting times
Posted: Mon Jul 31, 2006 3:23 pm
Hi,
There is a form on my site that requires that the user types in the start time and end time of down time. If this sounds confusing, check it out: This system logs the downtime for aircraft at my company, and the user must be able to type in the time the aircraft became out of service, as well as the time the aircraft became back in service. I need the PHP to calculate the difference and insert that number (in hours) into my DB, but I'm not sure how to do this since time goes doesn't work in intervals of 100, but 60. Is there some sort of built-in fuction to deal with this? What can I do to resolve this problem?
Thanks,
- Jeff
