local to gmt function doesn't work

I have just been testing.

I did a var_dump() on $timezone and config_item('time_reference') in the date_helper function now()

That's funny because when I run your code

PHP Code:

var_dump($timezone, config_item('time_reference')); 


i got

Code:

NULL string(14) "Asia/Singapore"

Where did you get $timezone variable?
I'm not touching any timezone in other places in my entire project. just started to work on it and only I changed the time_reference.

The now() is working perfectly as you can see you will get the correct timing of the region BUT the problem is the local_to_gmt() function that returns based on my server timezone (Europe/Berlin).

Do you know what's going on in the local_to_gmt() function?
