Comment 2 for bug 1822135

although through the log we can get the create time, it is hard to get a audit report through the regular project rest api. To get the create time, we have to dump the large quantity of logs which can make trouble in tow ways. One hand the log will not be constraint so it might be lost, the difficulty on getting the property will make the advanced operation impossible like sorting the project created from a to b. So, i do think adding project create time is quite necessary.
