NB, this was misaddressed - please check your addressee before you send. It
isn't ecos-discuss-owner!

Secondly, to answer the question, the I2C package provides I2C
infrastructure only. It does not provide a hardware driver. You need to
write an I2C driver and then a wallclock driver that uses the I2C
interface. I suggest starting at the I2C package documentation, and looking
at the existing m68k i2c hardware driver example.
