Here is an example solution: You could try creating a function in python that would randomly change your language setting every hour and then use this function as a base. After each hour, the script should generate a random English word from mymath.com/words list using the first letter of words starting with 't' (e.g., teachable, thoughtful). It then needs to find synonyms for that word through some kind of process and also need to create a unique identifier in its name which is generated randomly, but it should contain at least one special character(s), be 10 characters long, include the numbers '7' as the first two digits, followed by any seven-letter word from this list: [insert random selection method here] and end with "cursors". Additionally, incorporate a condition to check if it is currently between midnight (23:00) and midnight. If so, the function should execute only on Mondays, Wednesdays, or Fridays at 18:45 UTC+0h, excluding public holidays like New Year's Day. It must also check if it is a day of the weekend, avoiding execution during those days. If the time checks out and you're currently in London GMT (GMT) timezone, convert the installation date to UTC using an external API that gives accurate local solar times based on the user's IP address which can be assumed to be "https://api.timezonedb.com/data". The function must also check for prime numbers as part of its process and if it is a palindrome, skip this word from the list before choosing one at random, but ensure that when picking 20 words, they do not repeat any words used in previous choices within each individual selection. It should then create an output string combining these constraints:
