How do I create a Task with a Reminder? [CRM API]

Hello Zoho team,

how can I insert a Task with the "Remind At" field?
I've tried:
....
1 - <FL val="Remind At">2012-06-10 01:00:00</FL>
2 - <FL val="Remind At">10-06-2012 01:00:00</FL>
3 - <FL val="Remind At">10-06-2012 01:00</FL>
4 - many other variations on the date/time format

The task is created but the "Remind At" field is empty. Also, how can specify the "Repeat" and 
"Alert through Email" fields?

I tried:
<FL val="Repeat">true/FL>
<FL val="Alert through Email">true</FL>

and again, the task is created but the "Remind At" is disabled.

Thanks!!
