    Frank,

    I don't think that it has anything to do with boot up time. It is my understanding that cell phones get time continuously from cellular networks, and that most networks use GPS time rather than UTC. I speculate that it is easier to have the continuity of GPS rather than the occasional disruption of leap seconds of UTC.

    Cell phones receive the base GPS time, and it is up to the particular operating system as to whether to correct for the number of leap seconds. I believe that past Android operating systems did not correct for it, while IOS phones do.
