Zakaria,

Here's another example of the code. Run it and you'll see both objects have an age of 100 because of how the code sets the dBirthdate. But the both have different values for their associated oTime object and the object lifespan is output by the method I added.

oPerson1 = createobject( "Person" )
oPerson1.dBirthDate = datetime() - 100
? oPerson1.GetAge(), oPerson1.oTime.PointOfTime

messagebox( "delaying between the two people" )

oPerson2 = createobject( "Person" )
oPerson2.dBirthDate = datetime() - 100
? oPerson2.GetAge(), oPerson2.oTime.PointOfTime

messagebox( "letting the objects age" )

? oPerson1.ObjectAge(), oPerson2.ObjectAge()

DEFINE CLASS Person as Custom

cName = ""
dBirthdate = {//}
oTime = null
nAge = 0

function Init()
this.oTime = createobject("zaTime")
return dodefault()

function Destroy()
this.oTime = .null.
return dodefault()

FUNCTION GetAge()
RETURN  this.oTime.PointOfTime - this.dBirthDate
ENDFUNC

function ObjectAge()
return datetime() - this.oTime.PointOfTime
ENDDEFINE


DEFINE CLASS zaTime as Custom
PointOfTime = {//::}

function Init()
this.PointOfTime = DATETIME()
return dodefault()

ENDDEFINE
