Not a valid time format?

[Alexandre Machado]

I think you need to turn on the exception logger on your application so we will know where it is happening.

Have a look at this document. Enable the exception logger and the stack trace. It will show us where it is happening.

Regarding your date/time format, yes, it can be wrong depending on your system settings.
