[General Time Travel] I have a handheld time machine remote that can only travel up to five seconds in the past or the future. What useful things can be done with it?

1. Make a killing on the stock market with high frequency trading. You can probably stop here.
2. Use it as a replicator. Warning: Consider a mechanism for your remote to detect how many copies of it currently exist to prevent an infinite loop and the end of the world.
3. [Depending on what frame of reference your remote uses: Earth? Sun? Galaxy?] Use it as a teleporter. Warning: Very specific, very tiny travel duration required! Vacuum is not fun if you are not expecting it.
