Ok, I was just wondering where security became an issue. I was under the impression that this would be something the individual user could choose to display in their profile page. Like literally I'm asking as I can't conceive how this would be a threat.
But like I say over and again...I'm a noob so I'm not supposed to have the answers
That was my thinking too Onimua, just don't add a location if you are concerned, not quite sure how this could be a privacy issue at all, if you have a location the time can be worked out it would just be nice to have that info there.
There is no reliable way to derive your timezone/local time from a free-form location field. If my location is Paris, how can you tell if I'm in France, Canada, the US, etc? The user's local time should be based off their already existing timezone setting, perhaps with an op-in checkbox to display your local time on your profile.
I was thinking more of a clock than the digits and I like this idea. It's a hint at profile customisability and making it their profile by displaying information relevant to them. Local timezones on profiles would be a cute little feature. As for privacy, "Display Timezones on Profile?" checkbox would be fine, underneath timezone selection on registration.
