Date type "DT" not supported any more my recent TIA Portal/PLC-Firmware versions

The generated type DT in the *.scl file:

... 
_date: DT := DT#2018-4-24-16:21:45;
...

Is not supported any more. Instead the type "DTL" should be used. The formatting of the related data-value needs to be changed accordingly.

This bug depends on the used TIA-Portal version. In the .silecsdeploy it needs to be possible to specify the TIA Portal version. E.g. system="TIA_PORTAL_13".

The first TIA version which is affected is either TIA_PORTAL_13 or TIA_PORTAL_14. Andre Petit want to check. However it should be save to use DTL for TIA_PORTAL_13 ( assuming that Siemens introduced some overlap where both types could be used )
