Hi there, What is the best way to produce a timestamp that is synchronized (more or less, couple of seconds clock skew don't matter) among all running instances of an app?
The problem I need to solve is the following: In a mobile game, a user can use a certain boon, that is valid for 12 hours. I store a timestamp that reflect creation time + validity period. This is then persisted to the datastore. Of course then I need to check if this boon has expired by comparing current timestamp and the "creation timestamp + validity". So far I've been using simply "new Date()", but then I realized that this could very well differ if the clocks are not synced. Any thoughts?
