Indeed, it depends on the format you are using in your LDAP database. If
you are using a Unix time_t value, you can compare against $tod_epoch
using the <=> comparators; this is the most flexible because you can also
perform meaningful arithmetic with it. If you are using dates in ISO 8601
format (see RFC 3339) then $tod_log can easily be massaged into a string
which can be compared using lt/eq/gt.
