Set NULL value for a date field in resource

Hi,

The below code for setting NULL value on the end_date of a particular record in the resource table failed to clear the entry in end_date...

<set name='userview.accounts[GETGEE_Resource_EPS].end_date'>

<null/>

</set>

When i tried like

<set name='userview.accounts[GETGEE_Resource_EPS].end_date'>

<s> </s>

</set>

i got the below error;

Timestamp format must be yyyy-mm-dd hh:mm:ss.fffffffff

And when i tried with no space in the string

<set name='userview.accounts[GETGEE_Resource_EPS].end_date'>

<s></s>

</set>

i got the dumb result as in the null case...

Can anyone suggest me the way to go about... Thanks in advance
