bug: new feature to split log files isn't using correct timezone for file names of the log files

[slindner05]

Description of the bug

the log messages, themselves are fine and respect the timezone I set but the filenames are not.

Steps To Reproduce

configure timezone in docker config - in my case: America/New_York
configure the logger to rotate files hourly: log_file_rollover: hourly

compare the message timestamps in the file to the filename, itself.
