I never said to adjust it only once. For scientific use time should be specified as TTTT:TT:TT:TTTTT - PPPPPPPPPP where PPPPPPPP is the periods of cesium per second used for that measurement. For everyday use no need to distinguish the varying time 'constant.'
That was tried before 1972. The frequent adjustments of the length of the second became cumbersome to track, so the in 1972 the switch was made to the current system of constant length seconds with leap seconds to keep UTC tracking the rotation of the Earth..
