instead of removing this line, can you add time_type string? this will cause the specified time_format to be applied

@coffeepac
Thanks. Looks like time parameters (time_type, time_format,..) are only applicable to <parse> section of source plugin tail. If we use this params outside parse section in tail plugin then fluentd seems ignoring these params and we are getting the warnings.

I got the below errors/warnings when I tried to add time_type string , please correct me if I am wrong.
