Unify time range formatting.

The standard in https://orgmode.org/manual/Timestamps.html is
<start_time>--<end_time>.

Hi, I'll take a look at this this weekend. I'd like to implement some unit tests first (see #46).

Sure thing. Thanks Robert.

Hi, I'm reluctant to make this change. The reason is, when I schedule an entry with a
, the agenda shows me both the scheduled and the finish times on one line. However, when I schedule the same entry with a
, an extra line is added.

Hi Robert,

Sorry for the silence. I somehow missed the email notification.

org-gcal does not generate Scheduled entries. The format in the file is as following:

:org-gcal:
<2019-11-22 Fri 00:00>--<2019-11-25 Mon 00:00>

This shows within agenda just once.

What do you think?

Cheers, Slawek

Hi @zaks, I've been a bit remiss at updating the documentation (see #40). However, in #34 I modified the code to update the SCHEDULED property instead of inserting the timestamp into the :org-gcal: drawer if SCHEDULED is present, so that I can reschedule events easily using normal org-mode commands. It appears that using SCHEDULED does cause 2 lines to appear in the agenda, as I showed above. This is why I'm reluctant to merge this, especially because maintaining the two separate formats is not much more work in the code (for example, org-element will automatically parse both of them).
