Need to convert date-time and durations to ticks in PowerQuery
I've resolved the issue by adding a column with the number of ticks for the start of each day to my calendar table.
This gives me at least the tick count, though I've not (yet) investigated how this is affected by leap seconds and leap years in the future.
But for the time range 2000-01-01 until 'NOW' it appears to produce correct results and gets the job done.
For those interested in the code:
BljnTicks20000101 = Number.FromText("630822816"),
BljnTicksPerDay = Number.FromText("864"),
#"AddBljnTicks" = Table.AddColumn(#"Define PK", "BljnTicks", each (BljnTicks20000101 + (Duration.Days([Date] - Date.FromText("2000-01-01"))) * BljnTicksPerDay)

Hi Zoe,
There's no .PBIX yet because I am in the 'feasability' stage where I am testing if I can get access to all data I need.
I've build a fetch tester in PowerShell, and this fetches two test intervals from the web site as a test.
This works, and now I'd like to traslate this to Power Query (M) such that I can fetch the data with something like below.
The part in the PowerShell script that does the trick is (Get-Date $timestamp).Ticks but I do not find anything alike for PowerQuery (M).
StartTicks = (SOME CALCULATION),
EndTicks = (SOME CALCULATION),
Json.Document(Web.Contents(""https://WebSite.com?output=json",
[Query = [
start=StartTicks,
end=EndTicks],
Headers = [Authorization = Bearer]])),
Below the code in PowerShell I used to test that I can successfully fetch the page.
# QnD JSON FETCH TESTER
# Requires >= PS6.0
$Bearer = "1234567890abcdefg"
$Dates = "2020-04-10 00:00", "2020-04-11 00:00"
Foreach ($Date in $Dates) {
$start = (Get-Date $Date).Ticks
$end = (Get-Date $Date).AddDays(1).Ticks -1
$uri = "https://WebSite.com?output=json&start=$start&end=$end"
$OutFile = "C:\temp\fetch_day_$((Get-Date $Date).Day).JSON"
$response = Invoke-WebRequest -UseBasicParsing -Uri $uri -Authentication OAuth -Token (ConvertTo-SecureString $Bearer -AsPlainText -Force) #-UseBasicParsing ).Content
$response.Content | Out-File $OutFile
}
