At this time Content.ad does not support day-parting, or budget-pacing for campaigns. Rest assured we are working hard to introduce this feature in the near future.
That said, some tools such as theoptimizer.io allow for dayparting as one of their features. We still recommend against using these tools to daypart as our algorithm is not set up to allow dayparting. In general, you should never pause a campaign unless you are done testing that campaign entirely.
Pausing and unpausing a campaign repeatedly (dayparting) may flag your ads as inconsistent which will deprioritize your ads from serving, causing you to lose volume.
