Extracting total seconds from timestamps

Good Day all,

 

I need some assistance if possible. 

 

I am currently doing a calculation of time elapsed based between events on time stamps. The system stamps a change in event using the Unix time stamp. I did some table merging and some of the associated values return a null value (this is not the problem). What I want to achieve is to replace those nulls values with the local time so as to substract the local time from the time stamp. 

 

I used the following M function with no success:

Table.ReplaceValue(#"Expanded NewColumn2",null,Duration.TotalSeconds(Duration.From(DateTime.FromFileTime)),Replacer.ReplaceValue,{"NewColumn.system_time"}).

 

Please help!

 

Regards,

Abdul

Try

Table.ReplaceValue(#"Expanded NewColumn2",null,Duration.TotalSeconds(Duration.From(DateTime.LocalNow()-#datetime(1970,01,01,0,0,0))),Replacer.ReplaceValue,{"NewColumn.system_time"})

 

and it shall work.
