Is there a way of setting up a cronjob for a specific timezone?

My shared hosting is in USA (Virginia) and I am in UK. If I set a cron job to be executed at 1600 hrs every friday, then it will execute when its 1600 in Virginia.

I was wondering if I can setup my cronjob in such a way that it understands which timezone to pick. I am not too worried about daylight saving difference.

I have asked my shared hosting providers about it and they said I should be able to set the timezone in some cron ini files, but I could not find any.

cron controlpanel
