Insert, Update and Delete

5.1 Dealing with Time MySQL has a 14 byte datetime type which is very useful. The format of it is yyyyMMddhhmmss where: y = year M = month d = day h = hours m = minutes s = seconds So 19990317182330 works out to 6:23:30pm on March 17th, 1999. Having this numeric format is very useful because you can numerically compare dates to see if one is earlier than the other. Having each digit be a month, day, year, etc. means that you can quickly and easily create these dates. If you are requesting a date from a user, I'd highly recommend setting up a series of pulldown menus to build the date. One select field for each of the year, month, day, hour, etc. It's a lot of HTML to write out but it makes the backend code SO much easier. Just paste the multiple variables together in a string to create your date string. $datetime = $year.$month.$day.$hour.$min.$sec; Note: There aren't any corrections for timezone, you'll need to do those on your own. It's difficult with most web applications because the browsers do not export what timezone they are from in the HTTP headers. 5.2 Questions? Comments?
