Subject: LCD Clock ICs - Do Any Vendors Sell Them?

Can anyone tell me if any of the usual IC vendors sell the types of CMOS Clock ICs used in low cost LCD alarm clocks. Timekeeping ICs like the LM8562 and older LM8360 series are available for LED use but for LCD displays and low power applications all clock ICs seem to exist only in dice form attached to the circuit board under black epoxy. I need the equivalent ICs in packaged form. The alternatives and drawbacks are 1) a RTC plus microcontroller (consumes too much power), 2) use discrete CMOS ICs ( package count too high), 3) adapt LED clock chip to drive LCD (kludgy, high package count), 4) reverse engineer existing LCD clocks. Of these options, No 4 seems to be best if LCD clock ICs are not available. Can someone help to point me towards a source of these ICs?
