My Russian is not very good. I would translate it as either: 'love that stood the test of time' or: 'love eternal' or: ‘love forever’. It also depends on where you want to use the phrase.

Love is passed the test of time (an age old love). or It's a tried and true love.

My version as simple as one might say either "a time-proved love" or "a time-proven love "

Love withstands the test of time

I'm also not native speaker, but in simple language I would say: "Love time-tested";)))))
