this obviously does not work..

datetime(2.022051711034598e+16,'format','dd-mmm-yyyy HH:MM:SS')

N = 2.022051711034598e+16;
S = string(uint64(N))

S = "20220517110345980"

D = datetime(S, 'inputFormat','uuuuMMddHHmmssSSS', 'Format','yyyy-MM-dd HH:mm:ss.SSS')

D = datetime
   2022-05-17 11:03:45.980
