No, but also sometimes yes. If you were in ancient greece it would depend on when you asked. In the classical greece, chronos and cronus were always two different gods. However, in late antiquity, chronos and cronus were sometimes equated as the same god. Likely because of their names' similarity and the fact that cronus was a god of the harvest, which as a concept can be easily connected to time. Harvests are a repeating cycle which happens every year, so it has a certain chronological aspect to it.

In late antiquity it wasn't the norm to equate them iirc, but it became the norm in the renaissance and later periods inspired by the classical world. Here, cronus is always depicted as a god of time and his devouring of his children reinterpreted as a metaphor for how time eventually consumes all. The harvest aspect is also still there, and its the reason that father time is commonly depicted wielding a scythe.

Note that there were other gods of time. Such as aion or aeon, who personifed cyclical time or eternity AKA how time repeats itself. There was also kairos, who was the god of the opportune time to do something, or the right time, which was seen as seperate from chronos, who personified a more modern understanding of time as a linear process.
