[mrtg] rrd problem with timestamps from SNMP

Hi all,

I'm doing an SNMP poll to my APC Matrix 5000 UPS (community and ups name 
changed, but the MIB is valid):

Target[matrix-runtime]: at ups

This particular MIB will report UPS runtime remaining. I've tested it with 
a MIB browser, and with snmpwalk, and they both report the information 
successfully. When I run mrtg, however, I receive the following error:

WARNING: Expected a number but got '2:20:00'

Am I missing something and being an idiot, or is MRTG/snmpwalk not 
correcting for timestamps? I've seen people monitor runtimes before, but 
perhaps they are converting to minutes in an external script. Any ideas?

FYI - I am using rrd, not rateup.
