Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

%N Prime time display in hours, minutes, seconds on a six-digit 24-hour digital clock.
%C Leading zeros are ignored, so the term a(3) = 5, for example, corresponds to the display 00:00:05. Sequence has 7669 entries. The first 211 terms are the same as in A050246.

%e 109 is in the sequence because it is prime and display the time as 00:01:09.
