phpinfo() shows our system to be using \"\"Olson\" Timezone Database Version 2010.3\". I think that is now out of date, but can\'t locate an authoritative locatio
To do a complete timezone update (We had problems with incorrect Russia / Moscow timezone):
#for OS - CentOS and MySQL
yum update tzdata
mysql_tzinfo_to_sql /usr/share/zoneinfo
#for PHP
pecl upgrade timezonedb
pecl upgrade intl
#dependencies you may need for the above:
yum install gcc
yum install gcc-c++
yum install libicu-devel
