Agree, any truly wilted plant needs a drink immediately.
Checking plants mid-day can be misleading if there is faux wilt. Some plants can look wilty during the middle of the day but not really be thirsty at all. Checking for wilted appearance in the morning is a more sure thing.
I usually water potted plants in the evening because I don't have time in the morning to do it before I take a shower before work. I don't get the leaves wet much when I do it that with a spouted watering can. Ground plants get a drink from the hose in the morning on the weekends if needed, ideally. Sometimes that ends up being done in the evening too.
