Otherwise use the Number rules above. -- Fraction: Outputs the micro-of-second field as a fraction-of-second. The micro-of-second value has six digits, thus the count of pattern letters is from 1 to 6. If it is less than 6, then the micro-of-second value is truncated, with only the most significant digits being output. +- Fraction: Use `'S..S'` pattern for parsing and formatting fraction of second. + For parsing, the acceptable fraction length can be [1, `'S..S'`.length(<=9)] and with `[]` surrounded can be [0, `'S..S'`.length(<=9)]. + For formatting, with or without `[]` surrounded, the fraction length would be padded to `'S..S'`.length(<=9) with zeros.
