There seems to be an error with the date of a lab cache log in the statistics.
Yesterday (Nov 20th) I logged a lab cache in the morning (9 a.m. time zone of Mid-Europe / Germany).
In the statistics the number of Nov 19th was increased by 1 => wrong.
Today (Nov 22th) I logged another lab cache in the afternoon (6 p.m.).
In the statistics the number of Nov 22th was increased by 1 => right.
Maybe a time zone problem?
