Timezone Support

Timezone Support

[Russell Adams]

I've had a nagging issue with timezones. The timestamps in org do not
include TZ data, and I frequently switch timezones.

This impacts notes and agenda items.

Any ideas?

This is a very complex issue and I don't think I can fix this.

Sorry

Would it be practical to extend the time format to include TZ data
(ie: -06:00 ?). Otherwise I'll pick a TZ as standard and just mentally
convert from there.

Thanks.

No, I don't want to go there.  It is pandoras box.
Only in the neer-going-to-happen rewrite of Org-mode.

Yes, I think this is the only viable option.

I found this in an old drafts folder.  I just thought I send it in
case anyone still cared.

I had an idea come to mind if someone with the elisp-fu wanted to do
it.  You could put a flag in the file that gives the timezone the file
is in.  Say #+TIMEZONE: ... or something.  Then write a function that
will convert all the timestamps in the file from the timezone in the
#+ option to the current timezone and update the #+ to reflect the new
timezone.  Org-mode wouldn't even have to be aware of this.  You could
call it from a hook when you open org-mode files.  If there is no
timezone specification you don't convert the file.  It could probably
be an extension.

Reviving an old topic, it just hit me!

The only time I have to worry about converting TZ is when I'm entering
a date & time into the calendar.

Would it be possible for the calendar / date prompt to convert from
one TZ to the current?

ie: Wed 09:00 EST would automatically convert to Wed 08:00 (implied
CST, where I am).

Perhaps this is an easier fix.

Thanks.

Hi Russel,

I don't see a clean path forward with this, one that would work in a  
predictable way.  If yu travel, you will also be in different time  
zones when you write down appointments, sometimes you might have  
changed the time zone on your laptop, sometime not.  I can think of a  
number of ways how this can go wrong.

So for now:  No action.

Re: Timezone Support

[Russell Adams]

Assume the laptop and Org file is always in the same timezone, defined
by TZ.

If on entry the date is specified with another timezone (ie: 9:00 EST)
then it is converted to current TZ.

The conversion logic is one way to a fixed TZ.

Its not a critical feature, but I thought that was a good workaround.

Org-mode video coming soon!

Thanks.
