Ed Savage f355787165 [ML] Allow overriding timestamp field to null in file structure finder (#90764) ... Use a magic value of "null" for the timestamp format override to indicate to the analysis that a timestamp is not expected in the input text. This should improve performance when analysing delimited, ndjson or xml formatted text files that don't contain timestamps. For semi-structured text files without timestamps the magic value indicates to treat the text as single line log messages. see #55219		2022-10-12 09:08:25 +01:00
