Bug #15322
Updated by okkez (okkez _) about 6 years ago
~~~ Time.strptime("2018-11-20 Time.parse("2018-11-20 17:11:22.123", "%Y-%m-%d %H:%M:%S.%3N") # => raise ArgumentError: invalid strptime format - `%Y-%m-%d %H:%M:%S.%3N' Time.strptime("2018-11-20 Time.parse("2018-11-20 17:11:22.123456", "%Y-%m-%d %H:%M:%S.%6N") # => raise ArgumentError: invalid strptime format - `%Y-%m-%d %H:%M:%S.%6N' Time.strptime("2018-11-20 Time.parse("2018-11-20 17:11:22.123456789", "%Y-%m-%d %H:%M:%S.%9N") # => raise ArgumentError: invalid strptime format - `%Y-%m-%d %H:%M:%S.%9N' ~~~ But RDoc says that (https://docs.ruby-lang.org/en/2.5.0/Time.html#method-c-strptime): ~~~ %N Fractional seconds digits, default is 9 digits (nanosecond) %3N millisecond (3 digits) %6N microsecond (6 digits) %9N nanosecond (9 digits) ~~~ `%N` works fine for this purpose. I think we can remove %3N, %6N, and %9N from the document. In fact, Fluentd users confuse when they read [the document](https://docs.ruby-lang.org/en/2.5.0/Time.html#method-c-strptime) to configure Fluentd's parameter. See also #11220
