stop time later

is it wrong for me to sub-divide an hour? a day? i never know when to make the switch, when to identify something as occurring at the unit level. the thing is, i like to single out positive events, when applicable. and because these events may occur over varying periods of time, it seems likely that i would leave the dividing option variable in an effort to manage each individual circumstance. while i may allow an enjoyable week-long vacation to define a season, i would also like the option of pinpointing the second sip of the third mint julep experienced on a june evening as the pinnacle of all the sips i had taken that night. i know, i know, it's all a little crazy. perhaps i will return to the common usage of "hours", "minutes", and other such sub-categories of timekeeping. but i will do so with the knowledge that things won't be quite as happy around here.
