As KevinH has already suggested, having the plugin copy text to the clipboard would be the easiest solution and takes only 3 lines of code. Here's a proof of concept plugin:

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import sys
from datetime import datetime
from PyQt5.Qt import QApplication

# main routine    
def run(bk):
    app = QApplication(sys.argv)
    date_time = str(datetime.now())
    app.clipboard().setText(date_time)
    print('{} copied to the clipboard.'.format(date_time))
    return 0

def main():
    print('I reached main when I should not have\n')
    return -1

if __name__ == "__main__":
    sys.exit(main())
