VBA - Change the outbound and return times on Skyscanner

I've edited the original post but the actual flight is not that important, just being able to change the time ranges for the outward and return flights.

Try this link
https://www.skyscanner.net/transport.../170921/170928

This may help get an answer or help understand what I am trying to do:

1) Open the skyscanner link in internet explorer
2) Press F12 to open the webpage HTML
3) Select the "DOM Explorer" tab
4) Press Ctrl+B so that you can select a part of the webpage
5) Select the Outbound slider bar right handle (can be found on the LHS of the webpage)
6) It should highlight:

7) Just above this line is a line that ends with something like .....style="left:100%;">
8) If you move the slider bar, this value changes
9) The00:00 – 23:59
also changes when you move the slider right handle
10) It should be the values in either 8) or 9) that I want to be able to change/update via VBA

Note the following will get the time range values that it is currently:

Sub ChangeSkyscannerOutwardTimes()
Dim IeApp As Object
Set IeApp = CreateObject("InternetExplorer.Application")
IeApp.Visible = True
IeApp.navigate "https://www.skyscanner.net/transport/flights/Lond/BERL/170721/170729"
divElem1 = IeApp.document.getElementsByClassName("noUi-origin noUi-connect")
OutwardTimeLeftHandleValue = divElem1.Style.cssText
divElem2 = IeApp.document.getElementsByClassName("noUi-origin noUi-background")
OutwardTimeRightHandleValue = divElem2.Style.cssText
IeApp.Quit
End Sub()

I have found the rows and have updated the outward and return flight times in the HTML code BUT when I refresh the page, it defaults back to the original times: "00:00 - 23:59". How can I refresh the page so that it now uses what values i've input?

The lines of code relevant are:

IeApp.document.getElementsByClassName("filter-opts slider-opts")(0).getElementsByTagName("div")(0).INNERTEXT = "10:00 – 12:00"
IeApp.document.getElementsByClassName("filter-opts slider-opts")(1).getElementsByTagName("div")(0).INNERTEXT = "08:00 – 22:00"
IeApp.Refresh 'Note this refreshes the webpage but reverts the time ranges i've changed above back to "00:00 - 23:59"
