Use UTC internally to avoid ambiguous times Currently log4net uses local times internally and converts to UTC on output when needed (e.g. UtcDatePatternConverter). This can result in inaccurate UTC times during one hour each year when local time is ambiguous (DateTime.IsAmbiguous = true) for time zones that use daylight saving time. Also TimeEvaluator uses local time, which means it can trigger too early or too late when local time is ambiguous. This change stores current date/time as UTC internally, converting to local when required. No new unit tests added as to do so would require mocking DateTime.Now / DateTime.UtcNow, which isn't justified for such a simple change.
