[Peter Katzmann (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-29163?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=252774#comment-252774 ] 

Peter Katzmann commented on ASTERISK-29163:
-------------------------------------------

It is not a timezone problem because strftime works.
I poked around a little bit in the internet and there are a few messages about the similar problem.

One mentioned he had to disable optimization to get it working again.
So i changed the default compiler to the one who is standard for ubuntu xenial (gcc 5) instead of the standard bionic one (gcc 7) .

The gcc 5 version works as expected under bonic, also with gcc-8.

So it seems a problem with gcc-7 and optimization.
