"Nous aimons que tu sois à l'heure."

Bonjour Lisa, There are two verbs that could be used to say this: Nous aimerions que vous soyez à l'heure. Nous souhaitons que vous soyez à l’heure. Note that the first phrase the verb aimer is in le conditionnel; while the second phrase souhaiter is in l'indicatif. However, être is conjugated in le subjonctif in the clause of both sentences. J'espère que ma réponse vous aiderait. Bonne chance et bonne continuation dans vos études en français, la langue de Molière et qui a été utilisé par le monde français depuis l’époque d’Hugues Capet

I fully understand. One thing to keep in mind is that speaking French is not a race or a competition. You sound like me in that respect. I finally realized that the only pressure I was sensing to speak quicker was coming from inside me. Since you do not say where you live, I don't know what resources in the community you have, but the single best thing that you can do to augment your speaking ability is to find and join a French conversation class. If there is an Alliance Française in your area, they have great classes. If not, perhaps a college or university close at hand has non-credit courses that offer such a thing. Alternatively, private lessons with a native french-speaking person would do the trick too; however, this option may be the most expensive. Bonne chance et je suis très ravi que j'avais pu de vous aider.

"Nous t'aimerions être à l'heure" would be a literal translation of the English way to say this. It would, however, be wrong in French. Ron already explained the correct form to express this. I just wanted to respond specifically to the example you gave. -- Chris (not a native speaker).

Bonjour Chris, I really enjoy reading your input too. You have given me a lot more knowledge that I was unaware of. SVP, keep up the good work. Ron
