PHP Date Difference Primer Tutorial<\/p><\/div>\n

When you think of Timezones, do you think of datetime differences?<\/p>\n

Okay, well some<\/i> people must … surely?<\/font> Anyway, we do. We wonder, thinking about other people in the wooooorrrrllllddd, what time is it for them? Even, what day is it for them, the International Dateline blowing my tiny little mooooiiinnnnddd!<\/p>\n

And so we wrote some PHP code to help with datetime differences<\/i> whether they be related to Timezones or not. We designed a PHP web application that always starts with a defined “Start Datetime” and then allows either …<\/p>\n

    \n
  1. End Datetime (deriving Datetime Difference) … or …<\/li>\n
  2. Datetime Difference (deriving End Datetime)<\/li>\n<\/ol>\n

    … modes of use. Simple, huh?! And yet, even here, with that first scenario, a pretty fundamental thing was learnt, by yours truly, undertaking this exercise. A Datetime Difference<\/i> result is only useful to the “Day” point because any one “Month” can be a different length of time to another, and so, becomes difficult to express in terms of a “Month Difference”.<\/p>\n
