Your english is fine.
I'm still curious, but only if you remember. What version of weewx was your
last version and were you using Luc's raw.py with that (raw_0.4.x-lh.py
from the linked weewx-user thread), or was it the original that came with
mesowx?

Yes, That's good. That means the Davis driver is fine! (Phew!) :-))
And was the original missing the units entry on that line?

24 hours by default. That matches the time span for the 24-hour graphs.
The [Raw] section in your weewx.conf file has the following
# The max amount of raw data to retain specified in hours (set to 0 to
retain all data)
# This will in effect keep a rolling window of the data removing old
data based on·
# the time of the most recent record. It is recommended to set this to
at least 24.
#
# NOTE: if increasing this value (or setting to unlimited), keep in
mind that raw data·
# may consume VERY large amounts of space!
data_limit = 24
Once it's been running for a while (data_limit) you'll see the following
style of message every 5 minutes, that's raw.py cleaning up the old data.
raw: deleted rawdata prior to 2017-09-27 08:10:00 AEST (1506463800)

Nothing simple that I know of, however.
Looking at the code (in my case that's raw_0.4.1-lh.py, around line 128) ,
you could tweak the time value in
def newLoopPacket(self, event):
[...]
if dateTime > (self.lastLoopDateTime + 2):
where that last figure, 2 refers to seconds. If you change that value to 10
if dateTime > (self.lastLoopDateTime + 10):
then it should ignore anything falling within that 10 second span. You'll
get the timestamps that are > 10 seconds apart and the ones in-between will
not make it into the database.
And, I've just tested it on mine and that appears to work.
If you go down this path, save a copy of the file first, then make your
edits to the working copy. Better safe than sorry.
After those edits, you'll need to restart weewx
/etc/init.d/weewx restart

Probably best to visit the docs for that one.
http://www.weewx.com/docs/usersguide.htm#Meteorological_problems
and I'll go and read the MinMax section
