Hi Lee, It's not exactly what you asked for, but for your clock you might give this a try, or consider using the underlying DS3231 chip directly.
https://www.adafruit.com/product/255 It is basically a much more accurate and stable than usual 32KHz oscillator, with a TCXO that you can actually tweak programatically with a resolution of about 0.1 ppm.
