Dear Pikal, DEar all,

I do not if it could help:
if I print MyData%date, I get (at some point)

[281] "1998-12-10 16:00:00 CET"  "1998-12-10 17:00:00 CET"
"1998-12-10 18:00:00 CET"  "1998-12-10 19:00:00 CET"
 [285] "1998-12-10 20:00:00 CET"  "1998-12-10 21:00:00 CET"
"1998-12-10 22:00:00 CET"  "1998-12-10 23:00:00 CET"
 [289] NA                         NA                         NA
                 NA
 [293] NA                         NA                         NA
                 NA
 [297] NA                         NA                         NA
                 NA


Again Thanks

Diego
