How to synchronize timestamps across multiple devices?
The simple way is to use a single external source for time signals, such NIST, another internet source, or GPS as @Stefan suggests. Internet sources use NTP, see this Java NTP client question. The hard way is to do Clock synchronization between the devices. I am struggling with the same issue right now.
Why are timeseries 1 and 2 not synced?
I tried to sync (one of the outputs of syncing timeseries 1 and 2) with timeseries 3, but the results are not synced (e.g. the same length) (as shown below) because it simply has to do with the range of the time data: The problem is that the lengths of uniform_ts12_1, uniform_ts12_2, uniform_ts13_1, and length (uniform_ts13 are not the same.
How to synchronize more than 2 timeseries in MATLAB?
The synchronize () function only takes 2 timeseries arguments. What is the standard procedure if you need to sync more than 2 timeseries?
Is there a way to synchronize time on all devices?
You could agree on all devices on a certain time and then start it when the GPS tells you to. Essentially, you have two choices: the simple way or the hard way. The simple way is to use a single external source for time signals, such NIST, another internet source, or GPS as @Stefan suggests.
What happens to the server timestamp when persistence is enabled?
If persistence is enabled in the app, and the client writes the server timestamp token while it lacks network connectivity, the client will persist the token (and not the moment in time). The final timestamp will still only have a value when the client is finally able to synchronize that document.
How does server side email synchronization work?
Server-side synchronization runs on a schedule for each mailbox and has different synchronization delays based on the workload processed. Available workloads are incoming emails, outgoing emails, and appointments, contacts, and tasks synchronization.
Why does Firestore persist the server timestamp token?
No attempt is made to reconcile any latency between the client and server. If persistence is enabled in the app, and the client writes the server timestamp token while it lacks network connectivity, the client will persist the token (and not the moment in time).
