What were you trying to do that didn't work?

Extracting data from V3 archives on s390x architecture using pmlogextract does not produce any outcome

What is the impact of this issue to you?

pmlogextract does not work correctly with V3 archives on s390x

Please provide the package NVR for which the bug is seen:

pcp-6.3.1-1.el9

How reproducible is this bug?:

Always on s390x architecture

Steps to reproduce

1. Install pcp-zeroconf and pcp-testsuite on a s390x machine
2. Try to use pmlogextract with V3 archives from the testsuite

   # cd /var/lib/pcp/testsuite
   # pmlogextract archives/multi_v3/20150508.11.44 archives/multi_v3/20150508.11.46 archives/multi_v3/20150508.11.50 archives/multi_v3/20150508.11.57 /var/tmp/pmlogextract.output
   

Expected results

pmlogextract generates /var/tmp/pmlogextract.output archives with some data

Actual results

pmlogextract: Warning: no qualifying records found.
Archive "/var/tmp/pmlogextract.output" not created.

Comment

There seems to be some issue with the way how timestamp from V3 archives is processed on s390x . Using pmdumplog on the same archive generates different timestamps on s390x and x86_64, so probably the issue lies somewhere in code shared between pcp components:
