Parameter: ISODateTime_local

Date/Time (Local) ISO formatted
This standard is based on ISO 8601:2004(E) and takes on any of the following forms:
YYYY-MM-DDTHH:MM:SS[.xx]
2009-08-30T09:05:00[.xx] (local time)
2009-08-30T14:05:00[.xx]Z (UTC time)
2009-08-30T14:05:00[.xx]-05:00
The dashes and the colons can be dropped.
The T can also be dropped "by mutual agreement", but one needs the trailing Z if the time is UTC.

Note the Time Zone (TZ) as +/-HH:MM
Time Zone signage is for conversion from local to UTC
West Coast USA in summer is +7 (add 7 hrs to local time for UTC)
