Hi, I start to collect information regarding the lattice sieving
process done by cado-nfs using the information provided  by ETA (I
think).

So, what I see is that the inconsistent timing information within the
ETA printed there. What I see is something like this:

What i'm confused about is that the ETA printed something like this first:
(0.1% => ETA Mon Aug  6 12:38:24 2018)
then something like this:
(0.1% => ETA Tue Jul 31 07:12:02 2018)
(0.2% => ETA Mon Jul 23 02:32:21 2018)
(0.2% => ETA Mon Jul 23 21:13:38 2018)
(0.2% => ETA Fri Jul 20 11:53:13 2018)
(0.3% => ETA Sat Jul 21 10:10:17 2018)
(0.3% => ETA Thu Jul 19 09:26:08 2018)
and so on..


and as for when the ETA finally printed the quite constant date, (for
july 17 provided below, the timing is a bit odd (well, I mean the time
is counted down) just like this:

I don't know but maybe i'm reading it the wrong way or is there
something that I miss for this?

Thank you
