@

seconds since Jan. 1, 1970, 00:00 GMT, with fractional part.

The fractional part of the seconds field is of indeterminate length and precision. That is, the length of the fractional part of the seconds field will in general vary between findutils releases and between systems. This means that it is unwise to assume that field has any specific length. The length of this field is not usually a guide to the precision of timestamps in the underlying file system.
