Question About Sync Differences — Syncthing vs Obsidian Sync on Android (File Timestamp Issues)

What I’m trying to do

I’m trying to sync my Obsidian vault between my desktop and Android device using Syncthing with Remotely Save plugin instead of Obsidian Sync. The setup mostly works, but I’ve been running into an issue where the creation and modification timestamps of notes and folders don’t stay consistent.

On Android, some notes appear as if they were newly created, even though no content has changed. This seems to cause confusion with certain plugins (like those that rely on file creation dates for sorting or daily notes).

I want to understand whether this issue comes from how Syncthing and Android handle file metadata, or if it’s related to how Obsidian itself tracks and reads timestamps. I’m also curious whether Obsidian Sync handles timestamps differently (for example, internally tracking file versions or preserving metadata independent of the Android file system).

Things I have tried

I’d like clarification on:
1. Whether Obsidian Sync handles timestamps internally and avoids this issue.
2. Whether the inconsistency is mainly due to Android’s file system behavior.
3. Any recommended best practices for using Syncthing with Obsidian to keep timestamps consistent.

Some sync systems cause changes in file dates, so my first guess would be SyncThing. A search like syncthing file creation date may reveal if that’s the case.
