You claim that the output is incorrect without posting it here.
I think you mock about the 11 days missing, which is
a) correct according to the history of mankind
b) referenced in the manuals, at least on the AT&T SYSV line.

So, before claiming an error, and since you proved the output
on several machines, decide who is wrong: the command you issued
or your opinion about "what is a bug" !

Sincere
