ExifTool Forum

Hi all,
I have lots of photos in ".jpg" and ".png".
The photos have filename based on the right photo time like "2012-02-12 19.52.52.jpg" or "2012-02-04 23.59.54.png".

(1) for jpg
Now I can change the EXIF time for jpg by code:    exiftool "-datetimeoriginal<filename" -d "%Y-%M-%D %H.%M.%S.%%e" ./
Also I tried to change modify time and creation time by file name, however my filename format is not "YYYYmmdd_HHMMSS"
so the code     exiftool "-AllDates<filename" *  does not work is there any way without change file name format first?

(2) for png
I tried to change the modify time or creation time for png, and I referenced this article  https://exiftool.org/forum/index.php?topic=8831.0
the suggestion code   exiftool "-PNG:CreationTime<{filename;s/(\d{4})-(\d\d)-(\d\d) (\d\d).(\d\d).(\d\d).*/$1:$2:$3 $4:$5:$6/}"  does not work for me.
I am not sure if it causes by the new version.


Could anyone give some ideas for this. Any suggestion is appreciated!

Thanks!
Atai

Sorry, Im reading many times, but cannot understand the question inside '(1) for jpg'  ????
But for png its just looking like typo, because it should look like.... ${filename;

Edit: For the jpegs, to use something like -AllDates"<${Filename; s/YourFormat/GoodFormat/}" but this impossible to advise without knowing YourFormat.
Example: if YourFormat was like mm-dd-YYYY HH.MM.SS, then to use something like...
-AllDates"<${Filename;s/.*(\d\d)-(\d\d)-(\d\d\d\d) (\d\d)\.(\d\d)\.(\d\d).*/$3$1$2 $4$5$6/}"

I don't understand.  Both your examples have Year Month Day Hour Minutes Seconds in the proper order.  As per FAQ #5 (https://exiftool.org/faq.html#Q5), all you need is
exiftool "-alldates<filename" c:\images
Use of the -d (dateFormat) option (https://exiftool.org/exiftool_pod.html#d-FMT--dateFormat) is unnecessary.

For PNGs, you just need to add
-PNG:CreationTime<Filename

Example output
C:\>exiftool -P -overwrite_original "-AllDates<Filename" "-PNG:CreationTime<Filename" Y:\!temp\ccccc\p

As you can see, all the tags affected by AllDates (CreateDate/DateTimeOriginal/ModifyDate, see AllDates entry on the Shortcut tag page (https://exiftool.org/TagNames/Shortcuts.html)) have been updated and the PNG:CreationTime has also been updated in the PNG file.

I use the code   exiftool "-PNG:CreationTime<Filename"
then the png file got the creation time from filename
thanks a lot!!!
