By asking for the local time where your teacher currently is, you can also determine the difference in time zones.

Can you tell me the time difference between your country and Japan?
What is the hour difference between your country and Japan?
"What is the time over there?"
- You are simply asking what the time is in your teacher's country. "over there" meaning the place where your teacher is situated.
This is an indirect question since you may have to work out the time difference once your teacher tells you the current time in his/ her country.
Example:
You: What is the time over there?
Teacher: It is 4 o'clock in the afternoon, where I'm from.
"Can you tell me the time difference between your country and Japan?"
- In this sentence, you are being direct as you are asking your teacher the exact time difference instead of asking her/him what the current time in his/her country.
Example:
You: Can you tell me the time difference between your country and Japan?
Teacher: The time difference between my country and Japan is 7 hours.
"What is the time over there?"
- 相手（先生）の国のその時の時刻を尋ねています。"over there" は相手がいる場所を指します。
これは間接的な聞き方ですね。
時刻を聞いているので、時差までは答えてくれないかもしれません。
例：
You：What is the time over there?
（そちらは今何時ですか）
Teacher：It is 4 o'clock in the afternoon, where I'm from.
（こちらは午後の4時です）
"Can you tell me the time difference between your country and Japan?"
- 相手の国の（時刻ではなく）時差を直接尋ねる質問です。
例：
You：Can you tell me the time difference between your country and Japan?
（日本とそちらの時差はどのくらいかわかりますか）
Teacher：The time difference between my country and Japan is 7 hours.
（7時間です）
What is the time difference between our countries?
How many hours ahead/behind are you?
What time zone are you in?
You could ask them if they know the time difference between both countries.
You could also ask them this by asking how many hours ahead or behind they are from you? This is a common way of talking about time differences in English. We often say things like:
"Japan is seven hours ahead of us"
"Do you know how many hours behind New York is?"
"Do you know if the time in Nigeria is ahead or behind us?".
Saying it in this way is a reference to the lines of longitude that we work out time zones and differences from.
相手にお互いの国の間での時差について知っているか尋ねることが出来るでしょう。
相手の国が自国より何時間進んでいる（ahead) または遅いのか（behind)と聞くこともできます。こちらは英語で時差について話す際の一般的な表現です。例えば、下記のように使えます。
"Japan is seven hours ahead of us."
（日本は私達の国より7時間進んでいる。）
"Do you know how many hours behind New York is?"
（ニューヨーク時間は何時間遅いか知ってる？）
"Do you know if the time in Nigeria is ahead or behind us?".
（ナイジェリア時間はここより進んでいるか遅いか知っていますか？）
このように質問することは、タイムゾーンと時差を計算するための経度線に関連しています。
