The constructor new DateTimeOffset(logEvent.TimeStamp) infers the offset from the DateTime's Kind: Local/Unspecified uses the machine's local offset, while Utc uses zero. NLog's default TimeSource produces local DateTimes, so the resulting offset will reflect server-local time, which can be inconsistent across deployments and may cause confusion when correlating Sentry log timestamps. If a custom TimeSource yields DateTimeKind.Unspecified it will silently be treated as local. Consider normalizing to UTC explicitly.
