However, I haven't been able to find any information on the scope of
the putenv() statement. What happens if users from Vancouver and
Toronto log on at the same time?
Assuming you are running a multi-process web server like Apache1 or Apache2
with the prefork mpm, then there is no problem. The TZ env var will be
per-request.
PHP takes care of resetting it at the end of each request.
The PHP documentation says putenv() applies "for the current request"
only, but several users on the documentation page disagree. They claim
that putenv() has changed the time zone for both the current request
and other future requests at random.
They are either wrong, or they are using a multithreaded server like IIS.
There is actually a new ext/date extension on the way which provides
this capability
separate from the OS-level locale stuff you are looking at to attempt
to fix variances
at the OS level messing up portability.
