If you’ve ever had to deal with time and PHP before, chances are you’ve had to deal with time zones. Dealing with time is difficult enough, but once the time becomes variable based on the preferences of the user of your application, it becomes even more confusing.

Why so confusing? I mean, it seems simple enough doesn’t it?

Well, there’s a lot to consider:

How do you store the dates?
How do you store the time zones?
How do you do the math for adjustments?
etc.

Included in this page are the HTML select/dropdown code snippets to generate a list of time zones. It’s very hard to come up with a list of time zones that make sense because of considerations for countries and daylight savings adjustment. The list I use is based on a MySQL time zone list. If you want to use something else for the “value” attribute, feel free to replace it with something more meaningful to your needs, I often use the database identifier instead

Through enough research and googling, you can answer most of these questions. However, there came a time to decide how the time zone was going to be displayed to the user. In PHP you have some built-in options that are fairly handy. However, we wanted to show the user the time zone abbreviation. In addition, we had to match up what PHP does with the time zone options that we give our users. The time zone options are stored in our database like so:
