Hi All,
Does anyone know if the date/time format mentioned in the ExifTool FAQ , i.e. "YYYY:MM:DD hh:mm:ss[+-]hh:mm" is actually legal in an Exif tag, or only in an XMP tag? I ask because all the Exif documentation I can find tells me that date/time tags are limited to 20 characters (therefore no room for the timezone offset), but ExifTool will quite happily write more than 20 characters into, say, Exif:DateTimeOriginal, and the other tools I've tried all seem to read such files without complaint. I want to add timezone data to my images, but not in any way that will make them unreadable to any tool that's fussy about what it will accept...
Cheers,
Scott.

Hello,

I don't think this is legal use of this tag.
But I overcome this limitation by (mis)using GPSDateStamp/GPSTimeStamp, which stores UTC, while other date/time-fields usually store local time.

Many thanks guys, that seems like exactly what I need. Guess I should have searched a bit harder before asking the question though...

Cheers,

Scott.
