Probably the easiest way is treat everything as integers.

ss = fix(my_time-hh*3600L-mm*60L)
fsec = round(1E5*(my_time-hh*3600L-mm*60L-ss)) ;Fractional second
out = transpose([[hh],[mm],[ss],[fsec]])
print, out[*, 82300:82310], format='(i2.2,":",i2.2,":",i2.2,".",i5.5)'

Also, that way, everything comes out exactly the same string length, e.g.

23:58:57.64063
23:58:58.68750
23:58:59.73438
23:59:00.78125
23:59:01.83594
23:59:02.88281
23:59:03.92969
23:59:04.97656
23:59:06.03125
23:59:07.07813
23:59:08.12500
