What does the undocumented switch, `-t`, do for the `mdutil` utility

In the process of troubleshooting why my Time Machine setup was not completing any backup operations and hadn't finished backing my machine up since 4PM today — it's now 11:49PM —, I saw two suspicious console log entries as follows (btw: after a re-boot, Time Machine completed, but I'd still like to clean up my console log messages and/or spotlight, as the case may be):

*9/24/13 11:36:57.053 PM sandboxd[485]: ([484]) mdworker32(484) deny mach-lookup com.apple.PowerManagement.control (import fstype:hfs fsflag:480D000 flags:200000056 diag:0 uti:org.openxmlformats.spreadsheetml.sheet plugin:/Library/Spotlight/Microsoft Office.mdimporter - find suspect file using: sudo mdutil -t 9288141)*

and

*9/24/13 11:37:57.524 PM sandboxd[499]: ([498]) mdworker32(498) deny mach-lookup com.apple.PowerManagement.control (import fstype:hfs fsflag:480D000 flags:200000056 diag:0 uti:com.microsoft.excel.openxmlformats.spreadsheetml.sheet plugin:/Library/Spotlight/Microsoft Office.mdimporter - find suspect file using: sudo mdutil -t 2795200)*

I did as suggested, and rather than bore you all with that content (and have to figure out how to make it not auto-wrap in this field), here's the question:
What does the undocumented switch, -t, do for the mdutil utility? I've looked in the man page and several man pages online, and none document this switch.

Well, maybe I can format one of them:

whmcclos@mbp ~
$ sudo mdutil -t 9288141
dyld: DYLD_ environment variables being ignored because main executable (/usr/bin/sudo) is setuid or setgid

OK – that wasn't hard – here's the other (I'm gettin' tired!):

whmcclos@mbp ~
$ sudo mdutil -t 2795200
