[BUG] - org-agenda log view does not conform to org-timestamp-formats

[Tebe Nigrelli]

Steps to reproduce:

Changing org-timestamp-formats to include the timezone: ("<%Y-%m-%d %a 
%Z>" . "<%Y-%m-%d %a %H:%M %Z>"), a clock line will look like this:

(https://emacs.stackexchange.com/questions/13463/specify-timezone-in-org-date-format)

CLOCK: [2023-01-28 Sat 17:04 CET]--[2023-01-28 Sat 18:04 CET] =>  1:00

After toggling the "log view" in the org-agenda, the clock's line does 
not contain duration of the clock, instead showing "(-)" in the 
duration, as ongoing / error:

Expected behaviour: "Filename:   17:04-18:04 ┄┄┄┄┄ Clocked:   (1:00) 
Activity"

Shown behaviour:    "Filename:   17:04 ┄┄┄┄┄ Clocked:   (-) Activity"



Relevant:

Writing a duration ("%H:%M") at the 59th character of the clock 
line (where the duration would have been if the timestamps had normal 
length) results in the agenda reading the number and placing it in the 
parenthesis, suggesting that a fixed number of characters is skipped 
before reading the duration of the clock, for efficiency.

org-clock-report works as intended, so does org-ctrl-c-ctrl-c (fixing 
the date, writing the duration at the end of the line). The issue seems 
limited to the agenda.

Could be related to org-agenda-get-progress, but I am not sure.
