Fix dying with "Cannot read : No such file or directory" error #2

Closed alvm closed 9 years ago

alvm commented 9 years ago

The error comes from the _ReadEtcSysconfigClock() function and happens in case if it was called without passing a mandatory parameter to it.

Unfortunately, FromEtcSysconfigClock() calls _ReadEtcSysconfigClock() without parameters.

A simple test case to reproduce the issue requires to temporarily move /etc/localtime file to some other location and then run the following script:

$ perl -MDateTime -E 'DateTime->now(time_zone => "local");'
