What's the difference between "period" and "time"? Is it more correct to say "it rained at the right time" or "the rain happened during the right period"?
Logically if you're a farmer raining at MM YY DD HH MM SS (a specific time) is useless. You need it to rain over months for a couple hours in a patchy way non-continuous period.
Does "time" refer to an indefinite period or a specific quantum mechanical atom flashing?
- the indefinite continued progress of existence and events in the past, present, and future regarded as a whole. "travel through space and time"
- a point of time as measured in hours and minutes past midnight or noon. "the time is 9:30"
Time does refer to either a specific point or a bunch of indefinite infinite stuff, so according to this "it rained at the right time" is logically incorrect.
