Mention if one can use leading zeros,
09 00 01 05 * echo File SNOT-5554 form
02 00 01 20 * echo Nerdsburg Jr. wedding anniversary
to e.g., make columns line up, or will they be interpreted as octal, etc.

Hello Dan,
I would like to get more information about your intent, for this bug
report.
Should leading zeroes be supported for the sake of making columns line
up, or should leading zeroes be used to introduce octal constants, in
your opinion?
As far as I understand the code of the file entry.c, numbers are parsed
by the function atoi:
-------------8<- file entry.c's excerpt --
if (all_digits) {
*numptr = atoi(temp);
return ch;
}
-------------8<---------------------------
... which means that numbers prefixed by zeroes are considered as
decimal.
My opinion is that such an issue would not bother many people: numeric
entries stand for minutes, hours, days, day of month, mont, day of week.
So nobody need to write three digits to express such numbers.
In octal, 00 to 07 would mean the same as in decimal, and 08, 09 would
make no sense; so if one is in a doubt, one can give a try with 08 or 09
and see whether cron complains ;)
I am hereby closing this bug report. Feel free to reopen it if you want
to add something more about it.
Best regards, Georges.
