Hello,

How are you?

when ever I try to install a big script of my friends programming scripts, it says that

Warning: date() [func..etc] it's not sate to rely on the system's timezone settings.
please use the date.timezone setting. the TZ environment variable of the date_default_timezone_set()function. In case ....etc 

if you'll need the whole msg, let me know

Set an appropriate date.timezone value in the [Date] section in C:/Data/php/php.ini.
