This only affects how values are displayed, values are still correctly logged.
This error only occurs if timesheet period starts before the “Day light saving” time (for example March 10 02:00am) and worklog recorded is on daylight saving date. Since in this case 1h our is lost because, clocks are forwarded. So everything is shifting 1 day. If you set your period start to 11 of March you will not affected by this issue.
