I have problems with guild influence too. Would something like this work?

Whenever a character represents a guild and earns guild influence for logging in a data structure for that account is added to the guild roster data structure with the server time of when this character earned the influence.

When the server time for influence is reset any character that is no longer in the guild that data structure is removed. For any guild member character logging in that tries to earn influence simply look at the data structure and do a check for when the last time influence was earned.
