public void set_expiration_seconds (double seconds)
Set amount of seconds for how long harvested content is expected to stay alive.
Alternative function to [method@Clapper.Harvest.set_expiration_date_utc], but takes time as number in seconds from now.
It is safe to pass zero or negative number to this function in case when calculating time manually and it already expired.
