Heads up...TTSClock StrongBad files. I couldn't do anything about the date unless someone has the date wavs. I think you'll like it just the same.

Install TTSClock per the original instructions and before resetting to RO
Move the PCM files from the zip to your drive0\var\tts directory and the ttsclock file to drive0\var\ directory
reset to RO

This will replace the original am, pm, thetimeis, and ttsclock files.

Let me know if you get it working. I had a heck of time editing the file.
