application.timeZone only respected if using process.env.TZ, not an explicit value

[paulrobertlloyd]

If you set application.timeZone to Europe/London, the time zone is not respected.

But, if you set application.timeZone to process.env.TZ, which points to a environment variable with the value Europe/London, the time zone is respected.

This makes no sense. I thought it might be a case of passing the time zone to formatDate function, but that doesn’t make any difference either.
