[support] D7 Installation profile to change timezone settings..

Hi,

I am trying to make a custom D7 installations profile.. I have modelled it on the standard and minimal profiles and that got me started.. I am now trying to change the default timezone settings..

I have the following..

variable_del('configurable_timezones'); variable_set('site_default_country', 'GB'); variable_set('date_first_day', '1'); variable_set('date_default_timezone', 'Europe/London');

Lines 1 and 4 and not working and lines 2 and 3 are..

Line 1 is trying to change "Users may set their own time zone." under admin/config/regional/settings.

Line 4 is trying to set the default time zone.

Anyone got any suggestions?

TIA
