Right now Debian is in the middle of making sure that all of the 32-bit software has 64-bit time_t. Descendant distributions will benefit from their work.
Are other Linux distributions doing the same thing? Sure, and there was a lot of work in the kernel (mostly in the 5.x series) to get it all nailed down. NetBSD and OpenBSD already tackled it.
But "all" can't be guaranteed, because people insist on keeping elevator controllers and industrial processes and anything which hasn't actually had capacitors explode and resistors melt running for an extra decade.
