3-4 years back I did a library internship, that required us to enter the time when we arrived and left. The recorded time was totalled and written on the certificate. Sometimes I didn’t enter the right time! Probably 3-7 mins (more or less) earlier. The issue I realise now is that I wasn’t really honest in filling the time, so the time on certificate is not exactly in which I worked in. What should I do now, to compensate for my dishonesty? (Just to inform I haven’t used the certificate elsewhere to show it as an achievement.)
