Event Planner with timezone conversions for each member

[Kiint]

I'm looking for a mod which allows me to create an event which people can sign up to, but also show what times it is for their time zone. For instance, If I create a time for an event at 7pm GMT, what will it be for members in America? Members will be able to see the correct time for themselves and decide whether to sign up or not.

Any ideas?

I'm using vbulletin 4.1.10

Looking for similar.
vBulletin's calendar is cack though. Considering the amount we pay for vBulletin, you'd expect a much better calendar and more support for events built in as standard.

I'm still looking for something like this, maybe something that could be linked to the CMS so that we can see weekly events and sign up to them.

any ideas?
