Long-term enchantment type spells?

[Douglas Muir 406]

I'm looking for enchantment spells that can wait for a very long time -- months or years -- before taking effect. Does anything like that exist?

Put another way, imagine a situation where a high level caster can do a favor for you. In return, they want a guarantee of you doing one act for them in the future. As part of the deal, you agree to fail a saving throw against one spell. Is there a spell that will do the job here? Most of the obvious ones -- Dominate, Geas, and the like -- have durations that are measured in days. so that doesn't work.

Anyone?

This is pretty much exactly the geas spell. The duration is only if the task is open-ended. If it's a well-defined task with a clear means of completing it then it has no duration.

Agreed that Geas works as long as there is a "I'm done" condition. There's also Mark of Justice, which is permanent until triggered by violation of the condition.
