    24,[U3]m*"'%02d:%d0',
    "fe%~7<

This is pretty straight forward using printf formatting:

    24,                              e# get the array 0..23
       [U3]                          e# put array [0 3] on stack
           m*                        e# do a cartesian product between 0..23 and [0 3] array
                                     e# now we have tuples like [[0 0], [0 3] ... ] etc
             "'%02d:%d0',
    "fe%                             e# this is standard printf formatting. What we do here is
                                     e# is that we format each tuple on this string
        ~7<                          e# unwrap and remove comma and new line from last line
                                     e# by taking only first 7 characters
