Time change

[Craig A. Sharp]

Hello,

I am a bit confused on the upcoming time change.
I am in Michigan. Normally, I am 5 hours behind GMT. In the spring we move forward 1 hour and in the fall we move back one hour. We are currently 4 hours behind GMT. This Sunday morning we will be 5 hours behind GMT.

My TZ variable currenly reads:

EST5EDT

Here is my tztab file:

# Eastern Standard Time, Eastern Daylight Time
EST5EDT
0 3 24-30 4 1970-1973 0 EDT4
0 3 6 1 1974 0-6 EDT4
0 3 22-28 2 1975 0 EDT4
0 3 24-30 4 1976-1986 0 EDT4
0 3 1-7 4 1987-2038 0 EDT4
0 1 25-31 10 1970-1973 0 EST5
0 1 24-30 11 1974 0 EST5
0 1 25-31 10 1975-2038 0 EST5

I have looked at the man page for tztab and it is quite confusing. Based on this information, how can I be sure that the time change will occur as required.

Thanks,

Craig A. Sharp

There is no problem. See these threads:

Remember the timezone variable you should modify the TZ variable in
each of these HP-UX supplied files:

/etc/rc : for processes that are children of init, like cron
/etc/profile : for users of /bin/sh or /bin/ksh
/etc/csh.login : for users of /bin/csh
/etc/mkrs : for HP-UX recovery system

So, if users report that their time is incorrect after the change you can check
any of the above files.

Thanks for the info. This system does not have users. It is a database server for Peoplesoft. I checked the files out and also the provided links and I am comfortable about the time change now.

Thanks for the replies.
