The timestamp in Mendix logs is recorded immediately before the runtime begins sending the HTTP request. Mendix uses System.currentTimeMillis() for log timestamps, which is dependent on the operating system’s clock and may have limited granularity (see Oracle Documentation). This can cause events to appear out of order when comparing timestamps across different systems at millisecond precision.

Solution / Workaround

Do not rely on millisecond-order accuracy: Avoid drawing conclusions based on the order of events when timestamps differ by only milliseconds. This is not a reliable indicator of actual sequence.
