Seems like -d FMT does not work for 'IPTC:DateCreated'. Was this by design ?
Thanks.
exiftool -all -d "%Y-%m-%d" hs-2008-02-b-full-tif.tif | grep Date

The -d option works only for date/time tags, but unfortunately IPTC:DateCreated does not qualify.
If IPTC:TimeCreated also exists, then you can apply -d to ExifTool's Composite DateTimeCreated tag, which is derived from DateCreated and TimeCreated.
