cron job starts after timeout not after definition

[tripower]

Hello

my cron job definition is
'0 35 17 * * *'
so, it should run once a day at 17:35

to prevent maybe an other bug
(because job starts at 17:34:58 and runs so twice)
so I tried the attribute timeout '30sec'
but with that, the job starts after startup of the program and not at the defined time with defined timeout

17:35:30

any ideas?
thx

greetings
Klaus

update 25.07.2023:

results:
at PC1 with definition:
"0 35 17 * * *"
timeout: 30sec

START: 25.7.2023, 17:34:58
START: 25.7.2023, 17:35:01

at PC2 with definition
"0 35 17 * * *"

START: 25.7.2023, 17:49:43
START: 25.7.2023, 17:50:00

update 26.07.2023:
it seems to work with my sleep function inside the task
but this can only be a hack and not a solution!

update 28.07.2023:
START: 25.7.2023, 17:34:58
START: 25.7.2023, 17:35:01
START: 26.7.2023, 17:35:00
START: 27.7.2023, 17:34:58
START: 28.7.2023, 17:34:58

works with hack
but why start the job before 17:35???

my workaround

attribute at workerdata to set value for seconds
and
at the beginning of a cron task job
