Truncate the timestamps in the struct cifs_attr at the site of assignment to inode times. This helps us use the right fs api timestamp_trucate() to perform the truncation. Also update the ktime_get_* api to match the one used in current_time(). This allows for timestamps to be updated the same way always.
