You might say "beating around the bush" when they're wasting time talking about everything except what the subject should be. You might also say "killing time." "Wasting time" is actually an idiom in itself, as you cannot actually throw time away as waste.
To be 'as dead as a donut' is to be utterly dead, devoid of life (when applied to people, plants or animals) or finished with, unusable (when applied to inanimate objects).
The idiom 'sands of time' refers to the inexorable forward movement of time. It refers directly to the sand running through an hourglass.

Procrastination makes the problem bigger. The idiom itself relates to clothing that has become ripped and requires stitching to repair it. Failing to fix the rip will only cause the rip to worsen, which will inevitably require more stitching and therefore more time to repair -- 9 times more time according to the idiom. The idiom can be applied to any situation where regular maintenance allows you to spread the cost of that maintenance, rather than allowing faults to accumulate to the point where you have no option but to deal with them all at once, which typically ends up costing more time and money than if you'd dealt with each problem as it arose. A related idiom is "do not put off until tomorrow what can be done today", although this really means if you have time to do something today, then you'll have more time to do other things tomorrow.

This isn't an idiom. It means just what it seems to mean. Something is only a matter of time - you only have to wait until it happens.
