Well, your "feeling" is misleading. TOTP relies on correct time within a certain interval of grace period. The problem is the fault of Synology lacking a correct internal timekeeping source and the fault of paying money for other people's closed-source, faulty hardware. I have a Linux NAS running on a type-1 VM with passthrough to the actual disks. It also has TOTP when connecting over ssh but never has a problem because the hypervisor maintains the clock for all VMs and the on-board hardware clock is operable and has a battery.
