Exact time stamp for currency data (FX)

we can collect daily data from the finances of Oanda and Yahoo using the package quantmodas such:

getFX("USD/JPY",from="2007-01-01", to = Sys.Date())
getSymbols("EUR=X",src="yahoo",from="2002-01-01",auto.assign=F)

After carefully checking the data, you may notice that the values ​​from these sources vary significantly. Then I wonder, what exactly is the time to timestamp for each source? He doesn't look at midnight GMT.

I would appreciate it if you have a key. Thank.
