This exactly. Even if they didn't correct their clocks through NTP or other means, their clocks would only be slow by about 10 seconds or so over the course of 50 years. The servers/desktop PCs are likely to have been rebooted a few times in those 50 years, so they can correct the clocks in that downtine if they really must. As you mentioned, clock drift and corrections via NTP make thinking about implementations of 'leap seconds' for end user software a waste of time.
