Here is a question regarding the encoding of ASN.1 INTEGER vs. the
encoding of ASN.1 TIMETICKS.  I have an implemenation that encodes
INTEGERs according to the ISO spec, prepending a 0 byte if the number
is positive and the highest bit is set.  I do not do this for
TIMETICKS because the SMI specifies that type as "non-negative"
(section 3.2.3.5), and, since I assume that there is no negative
time, I don't prepend the 0 byte if the high bit is set.

Unfortunately, my implementation seems to adversely effect CMU code
derived agents, who are more than happy to set their time negative.
I imagine I will have the same problem with GAUGE and COUNTER types,
since the INTEGER is the only one that I prepend the 0 byte to.  I
could treat all these types like I do an INTEGER if I have to but is
this correct?

Also, which way is the correct encoding of a TIMETICKS variable
(prpending 0 for high bit set, or not)?

Thanks in advance!
	Mike
