First seen in this PR build: https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+pull-request-2/1289/consoleFull

This reproduces for me on master:

./gradlew :x-pack:plugin:ml:qa:native-multi-node-tests:integTestRunner -Dtests.seed=3B7BFF05D7416702 -Dtests.class=org.elasticsearch.xpack.ml.integration.ForecastIT -Dtests.method="testSingleSeries" -Dtests.security.manager=true -Dtests.locale=fr -Dtests.timezone=Cuba -Dcompiler.java=11 -Druntime.java=8

Failure:

> Throwable #1: java.lang.AssertionError:
   > Expected: <1544007600000L>
   >      but: was <1544009400000L>

I haven't found many recent failures like this in the CI mails so far, so I guess its only this specific seeds problem and I'm keeping the test unmuted for now.

I think this is probably a side effect of elastic/ml-cpp#327 and will cause a lot of failures. I will mute the test.

elastic/ml-cpp#327 changed the bucket timestamps the forecast is created, before it was at the beginning of a bucket, now it is in the middle.

This perfectly explains the error: 1544009400000 is 30 minutes after 1544007600000 and the bucket span of the test is 1 hour.

The test needs to be adjusted.
