I am having using the latest version of Hangfire (1.8.23) with SQL Server in Central Time (America/Chicago). The Hangfire Dashboard History Week Graph appears to shift daily job counts back by one day when viewed in Central Time. The underlying data and counters appear correct, but the visualization is off by one day.
On the dashboard:
- 6 jobs show as succeeded on 6/8/2026
- 1 job shows as succeeded on 6/9/2026
However, the actual Hangfire counters show:
- stats:succeeded:2026-06-09 = 6
- stats:succeeded:2026-06-10 = 1
The HTML shows UTC buckets:
- data-succeeded=‘{
“2026-06-10T00:00:00Z”:1,
“2026-06-09T00:00:00Z”:6
}’
It appears these UTC date buckets are being converted to local time in the browser, causing a one-day shift in the chart.
Is this expected behavior or a known issue? If expected, is there a supported way to display the graph in local dates instead of UTC-shifted days?
