When you post a message with a file attached (or anywhere you upload files on Rundl), you may see the message: "Request Time Too Skewed: The difference between the request time and the current time is too large."
This error indicates that operating system time on your computer/device is out of sync. For security purposes, Rundl requires the operating system time to be accurate within 5 minutes.
To resolve the issue you'll need to sync your time.
