[Opendnssec-develop] Making ODS immune for localtime changes

[Rick van Rein]

Hi Sion / others,

Thanks for thinking along:

Yes, I share that concern for one half of the globe.  We may have to
play a Phileas Fogg on them; preparing the database with time zones
on the safe side of UTC: "UTC-23h" or "UTC+23h" (not sure which),
and so on.

Alternatively, we could ensure that 2.0 resolves those issues by
not depending on timestamping, but on actual feedback from the
surrounding world.

Both variables would need our thinking through I suppose.  Setting them
to 1h + the actually wished-for variance sounds to me like a workaround,
but not an actual solution.  It's weird to have to set such variables
to a high value just because there *may* be a time shift every now and
then, and be delayed because of it throughout the rest of the year.


Cheers,
