Time Format User Readable

[Zafar]

I have this expression 

INTERVAL(FABS(AVG(Time_Diff))ddhhmm) in bar graph expression is used and i want the following format for expression which user can easily read   2 Days ,07 Hours ,30 Minute ,2 Sec  

Thanks

Perhaps doing lengthy way?

INTERVAL(FABS(AVG(Time_Diff)), 'DD') & ' Days, ' & INTERVAL(FABS(AVG(Time_Diff)), 'hh') & ' Hours, ' &  INTERVAL(FABS(AVG(Time_Diff)), 'mm') & ' Minutes, ' & INTERVAL(FABS(AVG(Time_Diff)), 'ss') & ' Seconds'
