Looks like there's no direct equivalent. Cronus looks like the Greek God of Time, and then there are some other time-related gods and goddesses, such as Horae - Goddess of the seasons, and indirectly Moros - which relates to Doom (which is sort of indirectly related to time). From my research:
Kronos: The God of Time
Kronos, the Titan god of time, is one of the most significant figures in Greek mythology. Sometimes depicted as an old man with a flowing beard, Kronos was often associated with the concept of time and the cyclical nature of life. He also had the ability to consume his children, which was thought to represent the inevitable passage of time and the fleeting nature of existence. In some myths, Kronos was eventually overthrown by his son, Zeus, who took his place as the king of the gods.
Horae: The Goddesses of the Seasons
While Kronos and Chronos were both closely associated with time in a general sense, the Horae were a group of goddesses who were specifically connected to the seasons and the passage of time throughout the year. There were three main Horae: Eunomia, Dike, and Eirene, each of whom represented a different aspect of the seasonal cycle. Eunomia, for example, was associated with the autumn harvest season, while Eirene was connected to the peaceful, tranquil time of winter.
Moros: The God of Doom
Finally, there was Moros, the god of doom, who played a crucial role in the Greek concept of time. Moros was responsible for determining the fate of mortals, overseeing the balance between life and death. He was often depicted as a gloomy, foreboding figure, who held the power of life and death in his hands. And yet, even as he presided over the passage of time and the eventual demise of all living things, Moros was also seen as a necessary force in the universe, ensuring that life continued to cycle in a natural, predictable manner.
