Updating Time Entries via API

Updating Time Entries via API

Hello,

I am trying to update time entries via the API. I am trying to update a custom field that is of type DateTime. I have figured out the format for the DateTime field as being "DD MMM YYYY, HH:MM:SS". I confirmed this by updating the "executedTime" with the above DateTime format. However, if I use this same format to update the custom field, it does not update the record.

Should I be able to update these fields via the API? If so, is there a different format to be used?

Thanks,

Nick
