Timezone issue

[mark1ra]

When I go on my page I get this error: :o

A PHP Error was encountered
Severity: Warning
Message: date(): It is not safe to rely on the system’s timezone settings. You are required to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected ‘Europe/Moscow’ for ‘MSD/4.0/DST’ instead
