How to query based on date in salesforce adapter?


Can anyone tell me, how to query the salesforce object by passing last date time field in where clause using salesforce adapter service.

I have given the where clause as “LastModifiedDate < ${lastmodifiedDate}”. That is i have passed it as “LastModifiedDate < 07/29/2013 14:30:00” and getting the below error message.

Error Message:

[ADA.505.1011] API Fault occurred while executing the call [query], Code: MALFORMED_QUERY, Message:
LastModifiedDate< 07/29/2013 14:30:00
ERROR at Row:1:Column:234
line 1:234 no viable alternative at character ‘’

Can anyone help me to resolve this issue?
