OK, CCris, I made plus some changes and finally I am getting the dates 
modified, created and last access. 

But, look at below the behavior of the EuCode with GTMs different, 
Greenwich and Bras�a: 


windows explorer dates with GTM = greenwich
modified= 2007/02/03 08:55
creation= 2007/02/03 18:18
accessed= 2007/02/03 00:00 

Eucode dates with GTM = Greenwich
modified= 2007/02/03 08:55
creation= 2007/02/03 18:18
accessed= 2007/02/03 00:00  

windows explorer dates with GTM = -03:00= Brasília
modified= 2007/02/03 08:55
creation= 2007/02/03 18:18
accessed= 2007/02/04 00:00 

Eucode dates with GTM = -03:00= Brasília
modified= 2007/02/03 10:55
creation= 2007/02/03 20:18
accessed= 2007/02/03 02:00  

However, the GTM is not being considered and this results in differences 
in the value of the hours. 

It is probable that we will have that to find which GTM is being used 
and to make additions or reductions in the value of the hour to show 
it correctly. 

But how meeting the value of the GTM in the machine that the Eucode is 
running?  

Many thanks again,
