Convert C# date ticks to DateTime

[winter69]

Is it possible to convert a column in Power BI that contains a C# Date tick value to a DateTime?

I am sure you could do it in Power Query. 

Read this. http://stackoverflow.com/questions/1489243/how-can-i-convert-ticks-to-a-date-format

in Power Query, add a new column and then use the formula, above to convert the date tick to a serial number

I think you can then convert the number to a date with the UI (although I have never tried it).  Worst case you should be able to use a power query date fipunction to convert it.

Try the following conversion

=DateTime.FromFileTime([ticks])-#duration(584388,0,0,0)

The FromFileTime counts the ticks from 1600/01/01 so that's why we have the duration of 584388 days to offset this.

Thanks Matt.  I suspected this was the direction I needed to go in, just wanted to be sure I hadn't missed something obvious.
