I think the problem is in the underlying Joda library that the date filter uses. When it sees H the builder [looks for](https://github.com/JodaOrg/joda-time/blob/890fb7b8801f7a8132464a8d558f410373918f96/src/main/java/org/joda/time/format/DateTimeFormatterBuilder.java#L726) one or two digits -- it is not limited to one. That will consume '94', which is not a valid hour.

You could use mutate+gsub to change the timestamp to "20210128 9.4501065" and then parse that using "yyyyMMdd H.mmssSSS"
