If you don't run ntp (or you machine is not attached to the network) the timer will count milliseconds without adjustment for leap-seconds. When the machine is switched off, the hardware clock likewise does not account for leap-seconds. When you switch on time is copied from the hardware clock. The system timer (which counts time since switch on) will not be adjusted for leap-seconds surely, as its perpose is to measure a time interval.
It doesn't imply that it runs in TAI. I would guess it usually runs UTC using the previous leap second count (assuming it was accurate to a second at all), until someone sets it again. Well, I think PC clocks are not very precise at all if they are not synchronized with external sources. Linux NTP client has the feature of measuring and then adjusting the relative speed of the system clock for a reason. If some people run their system clocks in TAI, how should a Haskell system detect whether it's TAI or UTC? -- __("< Marcin Kowalczyk \__/ qrczak@knm.org.pl ^^ http://qrnik.knm.org.pl/~qrczak/
