Dateconversion

#Caché

Hi Community,

 

I need to convert date 1997-08-09 10:38:39.700000000 into this format 1997-08-09T10:38:39Z 

I have tried using all date function  $ZDH,$ZDT no luck can anyone help me to convert this into required format.

Thanks,

Smythee

$Extract ($E) and $Translate ($TR) can provide a string manipulation

> set inDate="1997-08-09 10:38:39.700000000"
> set outDate=$TR($E(inDate,1,19)," ","T")_"Z"
> write !,outDate
1997-08-09T10:38:39Z

So steps are:

  • Grab the first 19 characters
  • Convert space " " to "T"
  • Append a "Z" to the end

Ignore if already the case, but would also recommend familiarity with $Piece, $Select and "[" (Contains operator) . $Find can also be efficient in string searches.
