i know that amp is on a 24 hour clock but something weird just happened to me. yesterday i got an amp survey at around 5:50 pm so i tried today at 4:50 pm to see if maybe they didn't set their clocks back and it actually let me take a survey and complete it. finished it around 5:02 and it has already credited. just wondering if their 24 hour clock said 5:50 or 4:50 when i started it and wonder what time i should try again tomorrow. really strange but i am not complaining - good way to start a new month.
