At 2.1, line 1, the First Carrier says it's 'four by the day', but when asked by Gadshill he says it's 'two o'clock'; then at 2.4, line 88, Hal refers to 'this present twelve o'clock at midnight', then asks Francis 'What's o'clock' - and then later asks the sheriff 'I think it is good morrow, is it not?', to which the sheriff replies 'Indeed, my lord, I think it be two o'clock'. Is there a significance to the repeated references to the time? And to the fact that both the carrier and the sheriff respond, when asked, that it is two o'clock? And why the discrepancy between what the carrier says to himself, and what he says to Gadshill?
