"Gravity doesn't literally bend spacetime. What it actually does is modify the spacetime interval. This modification can cause straight paths to appear to bend and time durations to alter to an outside observer. Because one of our convenient ways of thinking about spacetime is as one interwoven fabric where the border between time and space is a bit fuzzy, we say that gravity can "bend" or "warp" spacetime and alter the shape of this fabric/surface/whatever.
So to answer your question, time does not literally "bend". A massive object modifies the proper time interval around it such that an outside observer would see objects near the mass experience less time and spacetime intervals would have their spatial components modified accordingly. But that is a lot to say. It's much easier for us to simply say that gravity is spacetime being warped." -- https://physics.stackexchange.com/questions/192318/can-anyone-explain-me-how-time-can-bend-according-to-einstein-in-simple-way
