Nice choice with the Galaxy S10! Dealing with time zone resets is certainly not convenient, and we wouldn't want you to miss a meeting or anything due to this, so let's figure it out.

Also, as UpstateWinds stated, you can always modify your settings here (http://spr.ly/66011VPxZ). Keep us in the loop with your success and how this works for you.
