Hi i've read your descriptive and understand that you want to modify the date of creation of 5 files on google drive. However, modifying the actual date of creation of existing files is not possible at all. if it were allowed it would've ruined file integrity policies in google drive. You can however modify the "Modification date" of the file. If you want to change that then i can work for you. Please beware that what you desire is not possible even if someone states that he/she can do it for you.
For my experience, i've been programming for 4 years in C#, Java and some web based languages php. I have experience working in game development more than i have wth anything else. However, using REST APIs is something every programmer knows nowadays. I have integrated many REST apis into projects that i have done. Including OCR space APIs, Google Intelligent API's, Microsoft's Cognitive API's, Oxford DIctionary API's, Food encyclopedia APIs and many others. You can check out my profile below:
