Average date field in an aggregation

Dear @Zaakiy_Siddiqui, I have started to follow you because I am not yet decided if what you posted is from you or from ChatGPT.

What makes me lean toward ChatGPT is

  1. well formatted 3 steps list with embolden first sentence
  2. extra explanation of what is a timestamp being a long integer representing … epoch,
  3. the mentioned of using $toDate (if stored as a string or other format) while in the same post (but in your 2nd edit) you seem to blame @Kushagra_Kesav, for asking clarification. The schema is also clear about the fact that created is already a Date.
  4. sentences likein MongoDB, you would typically ”, "MongoDB does not directly …, it sounds funny
  5. in your 2nd edit, you use OP’s original post, and OP states. OP stands for original post, you use @ for Kushagra_Kesav, I think a human written text would also use @ Bolatan_Ibrahim to talk about OP author
  6. in you 2nd edit, you quote a set of matched documents in the aggregation, yet you shared an aggregation that does not use $match

What makes me lean for a genuine human written post:

  1. the error you made in the aggregation, in $group you $avg into the field averageTimestamp but in your last $addFields, you use the non-existing field averagecreatedTimestamp.

Finally, I am like Kushagra_Kesav, I have no clue about the matched documents or the avarage day.
