Using Subversion log in Continuous Integration Example

[modernrocketry]

I am using the Continuous Integration Example found in VBP 6.1
I am using Subversion version 1.5.5 (r34862)
compiled Dec 23 2008, 12:42:22

When I try to run the log command, I receive the following error:

2/23/2009 3:16:42 PM: Building project step 'Check (Subversion)'...
Error expanding macros or script in property Revision: {<Error in System (VBScript) script code at Line 81, Column 3 (Type mismatch: 'CDate')>

Can someone give me an idea what is happening here?

Apparently the value of the LAST_BUILD_TIME macro can't be converted to a date.
