When already viewing today, clicking Today now snaps the selected hour to whatever hour would be default for the current wall-clock time (same as a fresh visit to /vu); when viewing another date it still just jumps to today while preserving the current hour, as before. The link's href is built from the same todayTargetHour() decision as the click handler, so right-click -> open in new tab lands on the same target instead of following a stale href.
