looks like a bug in the imap4d's Dfmt(), trying to format a invalid %s.

the only %s is from mon[tm->mon] as far as i can see.

/sys/src/cmd/upas/imap4d/print.c:^Dfmt
	
	seprint(p, e, fmt,
		tm->mday, mon[tm->mon], tm->year + 1900, tm->hour, tm->min, tm->sec,
		sgn, off);

so we'd need to take a look at the tm structure here and see if tm->mon
is out of bounds or tm itself is invalid. it comes from date2tm()'s
first argument, which should be on the stack.

can you provide a snap?
