Yea, this is because of daylight savings time --- it will be OK tomorrow. --------------------------------------------------------------------------- PostgreSQL Bugs List wrote: > > The following bug has been logged online: > > Bug reference: 1128 > Logged by: J 6M > > Email address: j6m@adm.estp.fr > > PostgreSQL version: 7.4 > > Operating system: powerpc-ibm-aix4.3.3.0 > > Description: horology tests fails while make check (7.4.2) > > Details: > > On a powerpc-ibm-aix4.3.3.0, while doing make check with 7.4.2, > horlogy test failed.

Wow, that is bizarre. However, I think the tests are run with US timezones. Those errors are very similar to the ones I saw during daylight savings time here, and they went away the next day. I can't imagine anything that changed between 7.4.1 and 7.4.2 that would cause this. However, it is possible the US day changed during your tests. --------------------------------------------------------------------------- > ----- Original Message ----- > From: "Bruce Momjian" <pgman@candle.pha.pa.us> > To: "J 6M" <j6m@adm.estp.fr> > Cc: <pgsql-bugs@postgresql.org> > Sent: Tuesday, April 06, 2004 3:37 PM > Subject: Re: [BUGS] BUG #1128: horology tests fails while make check (7.4.2) > > > > > > Yea, this is because of daylight savings time --- it will be OK > > tomorrow. > > > > > > -------------------------------------------------------------------------- > - > > > > PostgreSQL Bugs List wrote: > > > > > > The following bug has been logged online: > > > > > > Bug reference: 1128 > > > Logged by: J 6M > > > > > > Email address: j6m@adm.estp.fr > > > > > > PostgreSQL version: 7.4 > > > > > > Operating system: powerpc-ibm-aix4.3.3.0 > > > > > > Description: horology tests fails while make check (7.4.2) > > > > -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073
Sorry, but ST to DT change occured on the last Sunday of March here. So it is not related to that. Moreover, I checked both 7.4.2 and 7.4.1 on the same day, and 7.4.1 was correct. ----- Original Message ----- From: "Bruce Momjian" <pgman@candle.pha.pa.us> To: "J 6M" <j6m@adm.estp.fr> Cc: <pgsql-bugs@postgresql.org> Sent: Tuesday, April 06, 2004 3:37 PM Subject: Re: [BUGS] BUG #1128: horology tests fails while make check (7.4.2) > > Yea, this is because of daylight savings time --- it will be OK > tomorrow. > > > -------------------------------------------------------------------------- - > > PostgreSQL Bugs List wrote: > > > > The following bug has been logged online: > > > > Bug reference: 1128 > > Logged by: J 6M > > > > Email address: j6m@adm.estp.fr > > > > PostgreSQL version: 7.4 > > > > Operating system: powerpc-ibm-aix4.3.3.0 > > > > Description: horology tests fails while make check (7.4.2) > >

The regression tests run in PST8PDT zone, and therefore the US
transition days are the ones that count, not your local ones.
This is even documented ;-) ... see section 26.2.3 in the 7.4 docs.
