According to the A4D docs, the JSON command *add selection to json* write
dates in IETF “Mon Day, Year” format (“Aug 27, 1931”). Is there any way to
decide on a different format? I can see that a map can be used to modify
individual field values, but is there a way to do this generically so I
don’t have to write mapping for each date field?
At the moment there is no way to change the time format. I'm going to add this to the next release of v7. In the meantime you can manually build the json for the selection and convert dates to whatever format you want.
