Start date displayed in Manager is based on _utime, which may be not the real start date
When displaying sessions in Manager, we displayed "Sessions started", which is based on _utime. But value of _utime can be modified to extend the lifetime of the session, so the information displayed is not accurate. This is the case for offline sessions where start date will always be in the future (as offline session lifetime is often greater than session timeout).
- First option: do not display start date, or just for SSO sessions, based on _startTime
- Second option: change the purge mechanism so we can handle different timeout values for different sessions kind
