如何使用strtotime（）解析不同时区的字符串

Question

I have an input string that will look something like

"Monday 2:00 pm" and I need to get a timestamp representation of this, but I cant figure out how to introduce different timezones.

For example right now I just simply do

 $name = "Monday";
 $time_string = "2:00 pm";

 $time_stamp = strtotime("$name $time_string");

which will get me a timestamp but say someone in 'America/New_York' inputs this v someone in 'America/Los_Angeles' the timestamps should be different correct?

Answer 1

I believe you can set the default timezone before you call strtotime:

date_default_timezone_set('America/New_York');

But the UNIX epoch is always in UTC, so I'm not sure this makes any difference to the timestamp:

// New York
date_default_timezone_set('America/New_York');
echo time(); // 1322309733

// London
date_default_timezone_set('Europe/London');
echo time(); // 1322309733
