Having said that, In American English it's acceptable to use' just' with simple past as well as with present perfect to express that something recently happened.

I have just decided to sell my apartment. ''just' as a time Expression'' can mean 'recently or very short time before' or after speaking. The word 'just' is commonly used with present perfect tense(most commonly in British English) to indicate that an action has recently happened and influences the present moment of speaking. A speaker choces the one which sounds best to him/her. Both of these sentences imply the same meaning but tense is different in them, which here doesn't affect their meanings. As john Lawler mentions in his answer 'Different speakers with different habits and experiences will probably see potential distinction or difference to make but nobody will see or make the same ones'. Must be differences in meaning between them'Īs far as the differences in meaning between these sentences is concerned, there is no real differences in meaning between them. The present perfect tense expresses an action that began in the past and is now completed in the present.I think this question is purely about simple past vs present perfect as well as British English vs American English.

Let’s start by talking about present perfect verbs. Verbs can appear in any one of three perfect tenses: present perfect, past perfect, and future perfect. In English, participles are also sometimes used to form compound words like “is going.” A past participle, in the context we’re using it today, is the second part of a compound verb that’s used to form perfect and passive tenses. Participles are words made out of verbs but used as adjectives. The perfect form is the verb tense used to talk about a completed action or condition and always uses a form of “have” or “had,” plus the past participle. The tense of a verb refers to the time of the action or state of being. Remember that verbs are words that describe an action, occurrence, or state of being. Today we’re going to be talking about the difference between present perfect, past perfect, and future perfect verb tenses.
