…elastic#46654) Currently DateMathParser with roundUp = true is relying on the DateFormatter build with combined optional sub parsers with defaulted fields (depending on the formatter). That means that for yyyy-MM-dd'T'HH:mm:ss||yyyy-MM-dd'T'HH:mm:ss.SSS Java.time implementation expects optional parsers in order from most specific to least specific (reverse in the example above). It is causing a problem because the first parsing succeeds but does not consume the full input. The second parser should be used. We can work around this with keeping a list of RoundUpParsers and iterate over them choosing the one that parsed full input. The same approach we used for regular (non date math) in relates elastic#40100 The jdk is not considering this to be a bug https://bugs.openjdk.java.net/browse/JDK-8188771 Those below will expect this change first relates elastic#46242 relates elastic#45284
