Date and Time settings issue faced in fedora 7 ..Need help

[dskonnur]

Hi ,

I have fedora 7 on my system . Now i have a doubt wrt date and time setttings .

Whenever i am setings the clock for 12 AM midnight ...

i can see that fedora provides me 24 hours also ! Actually after 23.59 the time change must be 00.00 ...but in my case its showing as 24.00 .

Please let me know , if any packages need to added or something's missing or have I deleted some specific file which takes care of this ?

Regards,
Deepak

On a 24 hour clock, midnight is 2400 hours, hence the 24:00 display. This is functioning as designed. Now, why do you want it to read 00:00?

However it should show 24:00 only for 1 minute.
after that it will show 00:01

Thanks for the link. Amazing what you can find in the Wikipedia. So, either 0:00 or 24:00 is acceptable. Pick your poison I guess.

Every thing on Wiki you get is what you put there. so if you got something true and cool. just put it there.

On a 24 hour clock, midnight is 2400 hours, hence the 24:00 display.

2400 is not part of the 24hr clock. The numbers used are 00-23 for the hour, 00-59 for the minutes and 00-59 for the seconds. Once the clock reaches 23:59:59 it should roll over to 00:00:00 as it is the start of a new day.

This is functioning as designed.

Not as designed but as programmed. If it were following the specs for 24 time it would roll over to 00:00

Now, why do you want it to read 00:00?

Because that is the proper way it should be done. I.e.,

~ $ date
Wed May  6 23:59:57 EDT 2009


~ $ date
Wed May  6 23:59:58 EDT 2009


~ $ date
Wed May  6 23:59:59 EDT 2009


~ $ date
Thu May  7 00:00:00 EDT 2009


~ $ date
Thu May  7 00:00:01 EDT 2009


~ $ date
Thu May  7 00:00:02 EDT 2009


~ $ date
Thu May  7 00:00:03 EDT 2009

The above roll over is from a RH5 system.

Well from what I read

Where convenient, the notation 24:00 may also be used to refer to midnight at the end of a given date—that is, 24:00 of some day is the same time as 00:00 of the following day.

it could be debated as to whether showing 24:00 vs 0:00 is incorrect. "Where convenient" gives a lot of leeway to the programmer. Anyway, if you want the clock to display 0:00 of the next day, instead of 24:00 of the current day, then change the source code...

[Lazydog]

I see no debate here. Also from that same source you are reading;

The notation 24:00 mainly serves to refer to the exact end of a day in a time interval.

Since time is does not stop the correct thing is to roll over to 00:00.
Time marches on.

Another way to look at this is the seconds on the digital clock.
Do they switch to 60 or 00 after 59?

[Rubberman]

Depends upon whether or not there is a leap-second that day...

Good answer. lol
