For comparison, this is what that looks like in Phix:
add/uncomment at the bottom of builtins\timedate.e

global function timedate_diff(timedate td1, timedate td2) 
    return timedate_to_seconds(td2)-timedate_to_seconds(td1) 
end function 

test code (same output):

include builtins/timedate.e 
 
set_timedate_formats({"DD/MM/YYYY","Dddd, Mmmm dd yyyy"},2) 
 
constant BIRTH_DATE = parse_date_string("28/6/1950") 
constant DATE2 = date() 
  
constant secs = timedate_diff(BIRTH_DATE, DATE2) 
constant days = floor(secs/(24*60*60)) 
  
constant d3 = adjust_timedate(BIRTH_DATE, secs) 
  
printf(1, "There are %d days between %s and %s. \n\n",   
          {days,  
            format_timedate(BIRTH_DATE),   
            format_timedate(DATE2)  
          })  
            
printf(1, "%s plus %d days = %s. \n\n",   
          {format_timedate(BIRTH_DATE), days,   
           format_timedate(d3 )  
          })            

I might add that the OE version should probably use datetime:format() to distinguish it from text:format().
