- This CL does two things, firstly, it ensures that all first & last
active times are monotonically increasing and independent of the
current system time. This allows us to better keep track of which
tasks are historical and should be hidden, and which are not.
Secondly, this CL moves the tracking of the last visible active time
into the system (per user) where it can be adjusted along with the
task active times when they are loaded.
- Following this CL, all active times in the future will be adjusted on
boot such that old tasks are made relative to the current boot time.
It’s not important exactly what time they are, only that they are
adjusted along with the last visible task active time so that we
always keep track of what is visible.
