Overnight usage booked to daytime

[#1]

I am on Plusnet value broadband which is unlimited between midnight and 8am.
My PC had a number of Microsoft updates to download (100's of MB) so I set it off at 00:05 this morning (20 Feb).
I have just checked my usage and the overnight usage for today is a mere 41.3MB.
The daily usage yesterday was a massive 1.46GB.
Have all the MS downloads been booked as daytime usage instead of overnight?
