Character sheet, pilot services tab will tell you to the minute when your Omega time expires. You will need to calculate the number of days between now and then.
Way out of the game is easy - just log off. Remaining game time and stuff is irrelevant if you aren’t enjoying yourself. Might want to donate your stuff to one of the in-game charities like @Mike_Azariah Magic School Bus or similar.
I think you missed the point. I would like to see my remaining Omega time without having to log into EVE or sign into account management.
Used to be able to check with Neocom, but CCP removed the endpoints and so no we see nothing.
I think it is a difference between the CREST API and the new ESI API. If I remember it right, CCP remover the endpoints for ESI or the Neocom developer didn’t add it to the Neocom II.
