Use DATE to set the serial date of a IPTC ExifTool entry, if the date appears in the EXIF data. It isn't currently possible to change the combined date and time fields, and the case-sensitivity of date fields depends on the local system. ExifTool's conversion activity is checked by any installed directory to assign lower-volume year, month, and day fields from the Exif date. The Exif entry will be correct only on Macintosh computers and on Unix the old-style date/time fields will be replaced by the ctime(3) representations. ExifTool's behavior in exiftool.exe on Linux appears to differ from the Unix compatibility mode in the ExifIFD.JPEG, and one solution may be to use exiftool.exe -D to permit the correction of case:
Not all time entries are represented by the "Establishment time" field. In some situations the "Establishment time" string will be part of a larger time item, which needs to be handled differently. Any techniques used to identify the time item will probably not work well on non-ASCII systems. For example, a Unicode language on a Macintosh (or at least the Japanese subset) employs three-digit time values.
The number of minutes to which the fractional time component is reduced. The default is 18. During reduction, the minutes are first regrouped into the last 18 hours (24 hours in the last minute), then reduced by one minute each time.
The "tone" describes the type of tone utilized for a particular tone entry. The default setting is almost any kind of tone. Tone 9 is typically used for signaling systems. Tone 7 indicates a bell, whereas Tone 8 indicates an alarm, and Tone 10 indicates a siren. d2c66b5586
