Epoxy, maybe? For the battery, not the Amiga!
The battery is kind of important these days. It can be a real hassle if the time is wrong.
Setting the time via internet can cause some programs to crash. Why? Because some programs depend on time only going in one direction. If your Amiga is slightly fast, setting it with the correct time causes the clock to go backwards.
I have written one application that won't crash, but you'll get screwey results.
