make_timesheet(simulate=True) logs at now_datetime(); when the suite runs late
in the day under the site timezone the 2h log crosses midnight, so its to_time
falls outside the report's `to_time <= end-of-day` bound and the submitted
timesheet is (correctly) excluded — making test_submitted_timesheet_in_summary
fail in an evening window (observed at 22:51 IST in CI). Pin the log to a fixed
mid-day window on today so the assertion is time-of-day independent.
