The relation of time to mass is actually inverse, as the following
sleight of hand proves:
1 amu = 931.494 x 10^6 eV
1 eV = 36.7502 x 10^-3 hartrees
1 hartree = 219.474 x 10^3 cm^-1
1 cm^-1 = 29.9793 x 10^9 Hz
1 Hz = 1 sec^-1
Thus, 1 amu = 225.239 x 10^21 sec-1 ;-)

but
Dr. Sanjay is asking to convert seconds to _mass_ units.
Anybody can convert time units to time units. Time to mass conversion is
somewhat less trivial !
