How can I get rid of the time zone in the date/time field?

So I have a GeoPackage with the following data:

enter image description here

and want to get just 2021-06-07 16:25:40

  • Which field type is this?

  • @Erik it is date/time field Commented Dec 6, 2021 at 13:31
  • Are you sure? Because using 3.16 I can't find an option to add the timezone to the datetime.

  • @Erik yes, I'm sure. Got this value from string using parsing function (gis.stackexchange.com/questions/212274/…): "QDateTime.fromString(fromval, 'dd.MM.yyyy h:mm:ss')". The timezone was unwanted. Commented Dec 6, 2021 at 13:40

In my QGIS (3.22), when I use datetime format, I get timezone information included by default. You can convert it to a string to get rid of it - use this expression, where datetime is the name of the field containing the datetime-information:

left(to_string(datetime), 19)

However, you can't use the resulting string field as a datetime field any more. Including timezone makes sense - as 2021-12-06 14:48:41 is not the same everywhere on Earth.

  • thank you! so there is an issue with the version? Commented Dec 6, 2021 at 13:49
  • No, I think including timezone is intended, that's not an issue. This format is not primarily intended for visualization - if you want to visualize, best convert to a string.

After inspecting provided GeoPackage I could not find the problem in any of your datetime fields, specifically "Save_times1" and "Loc1".



Proceed with RMC > Properties > Attributes Forms > Fields (see documentation) where change the Field Format from ISO Date Time into Date Time.




  • it's already date time, I've checked. I will share my data in a second. Commented Dec 6, 2021 at 14:20
  • @Taras: I downloaded the Geopacke provided by kartographinya and indeed, I get the same format, including timezone: i.sstatic.net/D4lOM.png This, however, is a visualization issue and I guess it has to do with system settings - QGIS just takes the options used by the operation system. As you see in my screenshot, if you try to edit a field, the timezone disappers.

  • So the question is why the timezone bothers you? In case you use several timezones, it matters, of course. If that is the case, I think you should reformulate the question or ask a new one. If you just want to use the time as a text somewhere, without the disturbing timeone text, converting the field to a string as proposed in my answer should work.

  • @Taras which version of QGIS do you use? Commented Dec 7, 2021 at 7:20
  • QGIS 3.18. and you?

You need to go to the field calculator. Then tick update existing field. Select your desired field and type:

regexp_replace( "date" , '(MSK)', '')

Then hit OK. Good Luck.

    thank you, but doesn't work. Commented Dec 6, 2021 at 14:02
  • You should replace "date" WITH YOUR FIELD NAME e.g. "date_field"! Then try again.

    Yes, I've done that Commented Dec 6, 2021 at 14:22
  • try `regexp_replace( "date" , '\\s(MSK)', ''). It must have worked. I've got confused right now.
