I'm in a quandary. Zimbra's SOAP response to an AuthRequest returns a lifetime value of 43199999.

Is it seconds? That many seconds is ~500 days.

But the lifetime is set to 2d:
Code:
% /opt/zimbra/bin/zmprov ga xxxxx@xxxxx.xxxxx.com | grep zimbraAuthTokenLifetime
zimbraAuthTokenLifetime: 2d
Any idea what this means?
