ITMS 7.6 Fist Time Setup portal shows the expires column with days left. If you upgrade to ITMS 8.0 the expires column in the First Time Setup portal will show as N/A if you have full licenses installed. If you look in SIM it shows a Days Left and an Expires column.
The expires column is used for when you have trial or extended trial licenses and displays when they expire. If you have license type full, the Expires column should display as N/A. The Days Left column will show how much time left in the AUP (Annual Upgrade Protection).
SIM displays the expires and days left correctly. In 7.6 the console displayed the days left value in the expires field which is incorrect. This was changed in 8.0 so the expires field will now show as N/A to match what is displayed in SIM. The 8.0 console does not currently show the days left column.
This issue has been resolved in 8.0 HF2 - See release notes for more information DOC9343
