How to deal with a timezone offset in minutes for geotagging?

[Walker59]

I would like to geotag my photos that I made in Nepal. But Nepals timezone is UTC/GMT +5:45 hours and ExifTool only allows hour offsets, not in minutes. It would be nice if minutes could be used as well, but for now:
Is there a simple workaround so that I get the correct co-ordinates written? I was thinking of giving the DateTimeOriginal an offset of 15 minutes, then geotag (with UTC/GMT +6 hrs.)  and then set the DateTimeOriginal back to what it should be. But maybe there is a simpler workaround?

Hi Jaap,

ExifTool supports timezones in the format +HH:MM.  If you have problems with this, please let me know the exact command you are using and maybe I can help.

Hi Phil,

Thank you for your answer and sorry for my confusion. I used the ExifToolGui and this Gui doesn't allow for minutes. Then I tried the command line on a single photo, which didn't work because I selected one that was just out of range of my track log... Other photos work great. I use:
-geotag "log.gpx" "-Geotime<${CreateDate}+05:45" "a.jpg"
And that works.

Thanks, Jaap
