Could you please come here on time tomorrow?
Literal
Tomorrow, time [in-accordance-with-どおりに] here [to-に] honorable-come humbly-receive can [polite-ますか].
時間どおりに = 'in accordance with (the) time' = 'on time.' ~どおり(に) attaches to a noun to mean 'in accordance with X.' The request uses おいでいただく — a polite combination of the honorific おいで + humble いただく — in its potential+ます form. A very formal 'could I have you come.'
