Since local time was adopted internationally, it's hard to achieve that just by observation.

First off, carbon dating only works on dead individuals.
It works by comparing the ratio of C14:C12 (C14 being unstable, and therefore will decay and reduce over time). A living individual will be continually taking-up carbon (of both C12 and C14), and replenishing their Carbon "stocks", but a dead individual doesn't take any carbon up, and the ratio of C12:C14 over time will change, as the C14 gradually disappears.

Secondly, carbon dating can only really be accurately used in the range of ~50 years to ~60,000 years, so the ages of samples older or younger than that cannot currently be determined.

well... carbon dating is an accurate method to get you the year the month maybe also the day for long decaying once alive materials.... but they never can give you the exact time even for recent material as its based on the principle of halflife of decay of carbon 14 and its only an approximation with a margin error of days not hours.... thats basically why its used in archeology where you need not know the exact time only the day will do and not used in legal medicine as we can never tell the exact time of death or birth

No, carbon dating is not that accurate, it can be off by about 4% plus or minus, depending on the age of the sample tested.

No, you can only get rough order of magnitude dates with carbon dating
