Timezone issue in BPM standard function

Hi,

We upgraded from NW 7.11 to NW 7.31 and I have moved all my BPM processes from CE to new PO environment. I am facing an issue with the standard function current-dateTime() in sap.com/bpem/glx/built-in/.

The issue is, it's returning the date time with timezone information like 2014-08-14-06:00. I am using the function as

date-from-dateTime(current-dateTime())

How do I get rid of the timezone information from the standard function ?

Thanks,

Yomesh
