This happened to me today on the leap-day. But worst of all it was a FTF.

So my local log-time was about 8.15 AM the 29.2. in southern germany. After loggin with Iphone app the log occurs in the Listing before the publishing an the day before (28.2). When i recognised that, i corrected the date by editing the log. In spite of the correction, neither the souvenier badge was in my profile nor the FTF-Entry in my GCstatistic was recognisable.
I am not that strong statistic cacher but anyway it was dissapointing.
