Garmin CIRRUS PERSPECTIVE SR22T Reference Manual page 79

If for any reason, a weather product is not refreshed within the defined Expiration
Time intervals, the data is considered expired and is removed from the display. The
age of the expired product is replaced by dashes. If more than half of the expiration
time has elapsed, the color of the product age readout changes to yellow.
The refresh rate represents the interval at which the GFDS servers make available
the most current known weather data. It does not necessarily represent the rate at
which new content is received from weather sources.
