For instance, in my father's work, timing matters enormously for buying and selling, and he would sometimes say or write to colleagues — without getting into specifics — that 'there's a right time for things.'
Literal
For-example, father [of-の] work [in-では], buy-and-sell [of-の] timing [topic-は] extremely important [copula-であり], he [topic-は] colleagues [to-に] minute details [object-を] not-saying, 'tide-time [quotative-と-いうもの-が] exist' [quotative-と] say, or write, [and such-たり].
A long sentence with several notable features. 潮時 ('the right moment, opportune time,' literally 'tide-time') is a metaphor drawn from tidal timing in fishing/sailing. ~たり~たりする is the non-exhaustive 'do things like X and Y' pattern. こまごまとした ('detailed, minute') uses こまごま, a mimetic for 'bit by bit, in fine detail.' Dense advice register.
