feature suggestion - add an option to set the time when day starts

Hi, I think Timekpr-nExT already has this feature, configure day intervals for every day from 9:00 to 23:00 or whichever hours you think he can start / finish using the computer and you're set.
Let me know whether this helps.

Sorry, I probably did not word my question properly.
 If I was able to set time period to 5AM-3AM(next day) that would be the feature I am talking about.

Now I'm confused :)

From the last comment I understand that you want to allow to use a computer from 5 in the morning (night) until the 3 in the morning (night) next day?

If I didn't understand that properly, can you please write what is the current limit per day for the user and what hours use can work and what hours are guaranteed sleep hours.

Example: user has daily limit of 6 hrs, he can work on computer from 9:00 in the morning until 1:00 in the morning next day, then they must go to sleep until 9:00 in the morning again. In this example I understand that you do not want user to spend that one hour at next days limit expense, but rather use spare time left from previous day, of course, if he has some left. Is that so?

As time reset at any other time than midnight is not daily limit anymore and that might be problematic, I'm trying to understand whether your use case can be implemented by tweaking current configuration.

Firstly thank you for your attention to that really minor convenience feature for really great product that beats most commercial parental controls :)

I think best way to explain the the problem is to have real life scenario:

let's say my kid has 4 hour daily limit and no strict bedtime.
if at 23:30 she has 45 minutes left, she will be logged out at 4 AM, while with desired feature would be to log her out at 00:15 :)

You can think of it as a weekly limit could be for a week starting either on Sunday or Monday, depending on country.

(I imagine that's not worth doing it, as probably code is stuffed with date comparisons, but definitely useful feature once/if you will create similar new software. )

Thanks again and feel free to close :-)

Yeah, this enhancement would be problematic currently.

.

Hi, I was wondering the same thing and found this question.

There is a "workaround" I'm currently testing: patch `datetime.datetime.now` to return the current time with a specific offset. This is usually a bad idea, but given the effort required to provide this feature, it might serve a purpose here.

This adds `retime.py` which replaces `datetime` using a lot of Python magic, and changes the desktop and service files to shift time by 1h.

Fyi I didn't experience any issues so far with the expected result ("midnight" at 01:00). In the meantime I realized that it is sufficient to set the environment variable TZ, e.g. TZ=UTC+4. With the same caveats: you need to keep the timezone difference in mind when setting times.
