Be careful with sometimes, sometime, and some time usage. :)
The adverb sometime (one word) means at an indefinite or unstated time in the future. As an adjective, sometime means occasional or former.
The expression some time (two words) means "a period of time."
The adverb sometimes (one word) means "occasionally, now and then."
- "He's been talking to just about everybody and wants to talk to you SOMETIME."
(John Updike, Rabbit, Run. Knopf, 1960)
-"You must give SOME TIME to your fellow men. Even if it's a little thing, do something for others--something for which you get no pay but the privilege of doing it."
-"I am so clever that SOMETIMES I don't understand a single word of what I am saying."
