PHP和Python显示不同的时间

Question

I have a Python application that stores the local time into a mySQL database and a PHP application that displays that date/time through a Web interface. I'm observing a constant offset (from GMT) of the displayed date/time.

I can find nothing in the PHP / Python documentation to explain this difference.

The Python application stores the local time:

import time
localTime = int(time.time())

The PHP application then retrieves the time and displays it:

 date('n/j/y H:i:s', $bg['last_polled'])

where $bg retrieves the entry from the mySQL database.

Why don't these two agree on what localtime is (both applications are running on same server)

Answer 1

As noted above, the timezone needs to be explicitly set. Ideally in a php.ini file. As a practical matter, I found at least two instances of php.ini and decided to take the coward's way out and add the following to startup.php:

date_default_timezone_set('America/Louisville');

The timezones for the US are far from intuitive (and largely depricated. I see a lot of entries to cover Indiana when parts of the state ignored DST)
