The details of your configuration are probably important here.  It'll be
difficult to give a clear, simple answer without that information.

However, if your have RRSIGs expiring this week then one of two things will
happen:  either they will be resigned this week, or your zone will go
bogus.  If you have RRSIGs expiring and you manage to delay the next
re-sign out beyond that date, then the signatures you have currently will
expire.  If you simply change the signature lifetime (and you have RRSIGs
expiring this week) then after your re-sign happens the new RRSIGs will
have the new signature lifetime, which would delay the need for the _next_
