No new database required - testnet chain height at the time of this post is 13895
I left the daemon running all night and this morning it was once again complaining about system time deviation and it never did get the blockchain fully synced (yellow numbers). So I manually resynced the time, updated to 0.1.1 and this new version definitely runs slower and is falling more and more behind trying to sync; i.e. - it started off around 500 blocks behind and after 15 minutes of running it is now 650 blocks behind.
As of now it looks like I won't be able to mine DERO at all with Atlantis because I either can't get the blockchain to sync or else my system time gets too far out of whack way before Windows bothers to check a timeserver again (which is every 12 hours by default). I can (presumably) fix the latter issue by running a 3rd party timeserver, but there isn't anything I can do about the daemon syncing slower than new blocks are generated.
