Saying '¿Qué tiempo es?' — This is a direct translation that is incorrect. 'Tiempo' means 'time' as in a duration (mucho tiempo) or 'weather'. For the time on a clock, you must use 'hora'. The correct phrase is '¿Qué hora es?'.
Using the verb 'estar' instead of 'ser'. — Telling time uses the verb 'ser'. Saying '¿Qué hora está?' is wrong. Always use 'es' (for one o'clock) or 'son' (for all other hours). Correct: '¿Qué hora es?'.
Confusing 'es la una' and 'son las dos'. — When answering, you must use the singular 'es la' only for one o'clock ('Es la una'). For all other hours, use the plural 'son las' ('Son las dos', 'Son las cinco', etc.). Saying '*Son las una*' is a common beginner error.
