With Twitter, your audience is spread across the globe, across different timezones... many of your tweets wont be seen by the rest of the world.

So, what is to be done if you want to catch the eyes of a set of users, say from London, when you're in San Francisco?

One way would be to tweet at their prime time, 7-9pm. To do that, you need to calculate what that will be in your time. But that may well be too early in the morning for you and is just too much of an effort to wake up and tweet at that hour.

ReplayTweet.com offers an alternate solution.

Just add the desired time zone to your tweets. e.g.#rpGMT, and the tweet will be reposted at around the same time in Greenwich Mean Time.

Mention any time zone on the globe, and go to sleep. We will repost the tweet for you.

Alternatively you can specify the number of hours after which you want to replay your post. Like this: #rp6h, and the tweet will be posted again after 6 hours.

We hope you enjoy this nifty feature. Enjoy !!!
