Due date cannot be set in Google Tasks API

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create: [GTLTasksTask object]
2. Set due date: patchObject.due = [GTLDateTime dateTimeWithDate:...];
3. Create: GTLQueryTasks *query = [GTLQueryTasks 
queryForTasklistsPatchWithObject:patchObject ...]
4. Execute: [tasksService executeQuery:query completionHandler:...]
5. Watch the error occur in completion handler.

What is the expected output? What do you see instead?

I expect the due date to be set. 
Instead, I see the following error:
------------
Error Domain=com.google.GTLJSONRPCErrorDomain Code=400 "The operation 
couldn’t be completed. (Bad Request)" UserInfo=0x6dac300 
{NSLocalizedFailureReason=(Bad Request), GTLStructuredError=GTLErrorObject 
0x6da0d20: {message:"Bad Request" data:[1] code:400}, error=Bad Request}
-------------

What version of the product are you using? On what operating system?
Just downloaded the latest version from SVN. 
Using iOS 4.3

Please provide any additional information below.

Use +queryForTasksPatchWithObject:tasklist:task: to set the due date of a task.

Note that +queryForTasklistsPatchWithObject: does not take a task identifier as 
a parameter.

Sorry, that was a copy & paste problem.. the step #3 actually uses 
[queryForTasksPatchWithObject:tasklist:task]

I think I found the root of the problem: whenever you create a GTLDateTime 
using [GTLDateTime dateTimeWithDate:], if the NSDate object contains a 
millisecond (such as [NSDate date]), then the 
[queryForTasksPatchWithObject:tasklist:task] works. If NSDate object does not 
contain milliseconds (such as [NSDate 
dateWithTimeIntervalSinceReferenceDate:(pass int here)]), then the update 
fails. 

GTLDateTime has a property called "milliseconds" and I think there's a bug 
around that.

Re-opening for investigation.
