I'm sure this isn't earth shattering.. but I'm curious.. because I've
never seen this before.. or noticed it.. what is with the

Beats me.  A google search indicates that it isn't unique to
this site, go ahead and ask in the LSTSRV and or LSTOWN list.
Pertinent info would be that it occurred on a site that had
experienced a variety of file damage including some garbaged
records in the PERMVARS file.

SWAG: I'd suspect that PERMVARS was tracking when digests were
last issued so, for example, a *daily* that had no activity for
a couple of days could reflect in the subject that it covered
an interval more than a day.
