Not days, but within a quarter of an hour. It measures alcohol intake constantly.

No. However, if you are referring to devices such as the SCRAM (Secure Continuous Remote Alcohol Monitor) Ankle Bracelet, built by Alcohol Monitoring Systems, those days may not be far off. Right now, the SCRAM is used in 20 states and is proving very effective in tracking offender recidivism 24 hours a day, 7 days a week, related to alcohol offenses. Continuous monitoring of other substances is a short leap.
About 72 hours for the urine test. Much longer for the hair follicle test. EtG (ethyl glucuronide) is an alcohol metabolite that remains in your body for several days after the liver has cleared alcohol from the bloodstream.
A 'regular' test can only show alcohol in urine until about 12 hours after alcohol intake. Very refined tests (not the kind that people stopped in traffic will face, though) can however detect some by-products caused by earlier alcohol use until about 60 to 80 hours - so 3 to 4 days - after the last alcohol consumption; shorter after only a modest intake, the full 80 days after heavy drinking.
