What is the date format in AdvancedCriteria? Any example is welcome

[prosper999]

myDS.fetchData({
_constructor:"AdvancedCriteria",
operator:"and",
criteria:[
{fieldName:'startDate', operator:"greaterThan", value:'2015-10-08 14:05:01 -0700'}
]
}, ...

The following is the error message:
java.lang.IllegalArgumentException: Parameter value [2015-10-08 14:05:01 -0700] did not match expected type [java.util.Date (n/a)] occurred.

Try "2015-10-08T14:05:01.000-07:00".

Or set the value in your criteria to a real Date instance and then take a look in the Developer Console RPC tab to see what value is sent in criteria.

I would like to ask how to set the value in my criteria to a real Date instance. Thanks in advance

With value: new Date()
