You'll want to ask the LDAP server for its time. We can assume that the
server's time will always be correct, while the client might mess it up
sometimes.

One way you could work around this is by writing a sumb HTTP proxy which
translates information queried from LDAP into Packages.gz, Release.gz,
and Sources.gz.
Granted, APT would have to parse those files over again. But you
wouldn't be grabbing needless data off the network.
