> Oh and the Clocks on your phone are GPS time and their isn't an easy way to change this

Sure there is. Go to settings and turn off automatic time setting. Then you can set the clock on your phone to any date and time you want.

Just because your phone uses GPS for navigation doesn't imply that it uses GPS for any other purposes, including setting the clock. It can, and you probably want it to, but literally nothing says it has to.

And even if you do continue to use GPS to sync your clock, your clock will not be off in 10-15 years because GPS time doesn't use leap seconds, so there's already an offset that gets applied to your clock when syncing time from the GPS signal -- currently this is 18 seconds, so your phone's clock is 18 seconds off from what GPS says it should be. And all this change means is that the offset won't need to continue to be manually changed in the future as leap seconds get abandoned entirely.
