Suntime
From Tardis Wiki, the free Doctor Who reference
Suntime was one of two seasons, the other being Icetime, that existed on Ribos for approximately 32 Levithian years. This was due to Ribos having an elliptical orbit around its sun. At this time the planet was hot.
The Ribosians believed that the season was caused by the Sun Gods, who they thought were fighting over Ribos with the Ice Gods. (DW: The Ribos Operation)
