+### Fixed
+- `getSystemDateAndTime()` now recalculates `timeShift` on every call instead of only
+  the first. Previously, if the device's clock drifted, was NTP-corrected, or the
+  device rebooted after the first calculation, `timeShift` stayed stale for the life
+  of the `Cam` object and every subsequent WS-Security-authenticated request would
+  keep failing (seen as persistent 400 errors) until a new `Cam` was created.
