Remarks

This event fires when the OS needs to change access and modification times of the file, identified by either Path or FileContext. The ATime and MTime parameters contain the access time and modification time respectively. All date/time parameters in the class are specified in UTC

To convert the values of the ATime and MTime parameters to Unix time, file_time_to_unix_time method.

The ATimeNS and MTimeNS parameters contain the subsecond part of the ATime and MTime date/time value respectively, counted in nanoseconds.

The ResultCode parameter will always be 0 when the event is fired. If the event cannot be handled in a "successful" manner for some reason (e.g., a resource isn't available, security checks failed, etc.), set it to a negative error code value (e.g. -ENOENT to indicate that the file does not exist) to report an appropriate error. Please refer to the Error Reporting and Handling topic for more information.
