History showing two days back not one?

Why is my self.History(1, Resolution.Daily) giving me 12-17 when the log shows 12-19? I have attached a debug to see in the log for reference. 

I know that my start date is 12-18, but the log doesn't throw the debug until 12-19 (also - why not 12-18?) so shouldn't my debug with self.time[-1] for self.History return 12-18 in that case? 

Any help would be greatly appreciated!

Here is a snip of the log that I am referencing -

Hi Enzo Ferrari ,

When the algorithm subscribes to Daily data and schedules an event, this event can be triggered as a "past event". For example, when data from 20181219 00:00 is streams through the algorithm, the event is triggered at 20191218 09:31. It is a resolution particularity that can be solved by subscribing to minute-resolution data.

At 20191218 09:31, the algorithm makes a historical data request for daily resolution. The last data available closes at 20191218 00:00. The variable that the algorithm is (opening) Time while it should be closing time (EndTime). 

for slice in history:
bar = slice[self.syl]
self.open.append(bar.Open)
self.close.append(bar.Close)
self.high.append(bar.High)
self.low.append(bar.Low)
self.volume.append(bar.Volume)
self.time.append(bar.Time)
self.Debug(f"{self.Time} -> {self.open[-1]}: {self.close[-1]}: {self.high[-1]}: {self.low[-1]}: {self.volume[-1]} {self.time[-1]}")
