interesting question, near perfect triangles
07:18:18
16:41:41
09:23:23
but non of them are mathematically perfect triangles.
well 00:00:00 and 23:59:59 are
for a perfect triangle all three hands need equal distance from center. hours range 0 to 23, minutes and seconds 0 to 59, so you need
h(divided by) 23 to equal
m(divided by) 59 to equal
s(divided by) 59.
since 23 and 59 are both prime, bad luck.
