format-time-string bug

[Marcelo Toledo]

A few days ago I was coding something related to time, then I needed to
use the function `format-time-string´ and the code above shows what I
have found wrong:

(setq t1 (current-time))
(sleep-for 3)
(setq t2 (current-time))
(format-time-string "(%H:%M:%S)" (time-subtract t2 t1))

the result of the last expression should be something near 00:00:03.

For me it is appearing 20:00:03. For other people it's appearing
diferent values but never what I am really expecting. Could someone
please try?

time-substract is returning the correct value, in this case something
near (0 3). The data format is a list of 3 integers. The first has the
most significant 16 bits of the seconds, while the second has the least
significant 16 bits.  The third integer gives the microsecond count.

I didn't have time to identify witch function is bugged yet, but, if
someone more experienced could identify what is wrong, would be nice.
