Made getFingerprint return null if it cannot find a match.
Fix two issues with the timestamp adjustment code:
1: if the begin/end timestamps are the same (or within 2 minutes of each other) then the test
for the begin timestamp being older that 1 or 2 days is not made (thus you
can ask for data as far back as you wish);
2: if both timestamps are older than 2 days, only the start tiemstamp is adjusted yielding a "start
after end" error from AWS.
