It depends on where you do the smearing. In a scheme I'm working on, the kernel clock keeps true (non-smeared, non-Posix) UTC time internally, but deals in smeared time on legacy Posix interfaces. But there are also ways of getting and setting true-UTC time, for applications that care, and this would naturally include those (like NTP) that are responsible for time synchronization with other systems.
