I want to display a time in a fixed timezone.
A script that I am using and modifying has this code:

list($hour, $min, $sec) = preg_split ("/-/", Date("h-i-s", Time()));

This gives me three values: $hour, $min, $sec of the current time.
This is used for calculating angles for a clock on my webpage.
So far so good. The clock works fine.

But, now I want to diplay another time, not the user-time, but a fixed
UTC-time.
I've discovered that the Date Function returns a lot of values, one of those
is Z -> the UTC offset in seconds.

I have changed the code:

list($hour, $min, $sec, $utc) = preg_split ("/-/", Date("h-i-s-Z", Time()));

I hope the above will give me four values: $hour, $min, $sec and $utc .
I want to use the UTC-offset to calculate a time in a fixed timezone.
To get UTC=1 I need the following formula:
HOUR - UTC_TIMEOFFSET + 1

I have translated that in PHP-code like this:

$hour = (($hour - ($utc / 3600) + 1)

But, the script does not work. What do I do wrong?

thanks,
