Sales chart doesn't add up?

I'm looking at the Sales chart under My eBay / Selling and if I look at all the daily sales figures shown on the graph, they don't add up to whats actually been sold.  Look about 10% off so wondering what these numbers are based off?

For example for today it says I've sold £23.18 but I only have 2 orders:

13.90 and 5.99 which gives £19.89

I'll answer my own question - a bit more digging looks like it's caused by time zones. 

I sold a item at  13 Apr 2024 at 11.56pm BST and eBay include it in todays sale so thining it might UTC based
