The time in certificates is represented by either a UTCTime or
GeneralizedTime structure. You aren't allowed to omit the expiry date
and you can't have a certificate that literally never expires but you
don't need to.

The limit for UTCTime is 2049 the limit for GeneralizedTime is 9999 but
not all software packages support GeneralizedTime.
