How do I make my Power Query formula accept timezone with decimal points

[newpi]

Hi,

I want to create a Power Query Formula, which uses a Parameter that my users can manipulate called as Time Zone. The Parameter type for #Time Zone is decimal right now so it can accept positive & negative values with decimal points.

I have a 'datetime' column called Time in (UTC). I want to create a Power Query formula such that I can pass the parameter #Time Zone which would convert Time (UTC) column to match that time zone and update the values in the column. 

Eg: if UTC datetime value is 

8/20/2020 14:10:15 UTC

 and my #Time Zone is +5.5 (5:30 mins) then above value should change to 8/20/2020 7:40:15 PM (8/20/2020 19:40:15  IST)

or if my #Time Zone is -5 (5:00 ) then my time value should change to 8/20/2020 9:10:15 AM (8/20/2020 09:10:15 ET)

I may have to change the datatype of my #Time Zone parameter from decimal to time or duration according to soultion which is fine but I would prefer in Decimal.

Hello @newpi 

You can use the function DateTimeZone.SwitchZone to accomplish this. This accepts a number to switch the zone. In case you want to use another format afterwards, you could create a function where you manipulate the format, before passing it to the function DateTimeZone.SwitchZone. Here the code

let
    Source = #table
    (
        {"TimeZoneUTC"},
        {{DateTimeZone.FixedUtcNow()}}
    ),
    Add= Table.AddColumn
    (
        Source,
        "Your time",
        each DateTimeZone.SwitchZone([TimeZoneUTC],5.5)
    )
    

in
    Add

Copy paste this code to the advanced editor in a new blank query to see how the solution works.

@Jimmy801 I want to use a parameter here and my parameter name is  "#Time Zone" .

I do not want to add column as there are dependant columns to my existing one, so want to edit my formula there itself.  My current formula is : 

The above formula is working fine when #Time Zone Parameter is whole number like 5 but not working when its a decimal like 5.5

Hello @newpi 

then change the formula to this

= if #"Daylight Savings" = true then DateTimeZone.SwitchZone([#"Activity Time (UTC)"],#"Time Zone" +1) else DateTimeZone.SwitchZone([#"Activity Time (UTC)"],#"Time Zone")
