  A frequency stabilized laser referenced to an unperturbed atomic two level
system acts as the most accurate clock with femtosecond clock ticks. For any
meaningful use, a Femtosecond Laser Frequency Comb (FLFC) is used to transfer
the atomic clock accuracy to electronically countable nanosecond clock ticks.
Here we propose an alternative clockwork based on the phenomenon that when an
atomic system is slowly evolved in a cyclic path, the atomic energy levels
gather some phase called the geometric phase. This geometric phase dependent
energy shift has been used here to couple the two frequency regimes in a phase
coherent manner. It has also been shown that such a technique can be
implemented experimentally, bypassing the highly involved setup of a FLFC.
