How to Fix Event Timestamps Wrong From Device Clock Skew

A player with a misset clock produces events dated next week, which scrambles funnels and retention. Capturing client time alongside a server-derived correction keeps ordering sane.

How to fix it

1. Record client time on the event

Stamp client_ts when the event is created so relative ordering within a device is preserved even offline. This is your ordering key on-device.

2. Correct with a server offset

On upload, compute the difference between the device clock and the server's receive time and store a corrected timestamp. This anchors absolute time without trusting the device clock.

3. Keep both timestamps

Persist client and server times separately so analysts can choose device-relative ordering or wall-clock accuracy. Overwriting one with the other loses information you cannot recover.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
