Abstract: The present invention 10 discloses a container 14 having a stationary ring 16 and a rotative ring 18 disposed near the top portion of a bottle. The stationary ring 16 is labeled incrementally with time periods, such as hours, with smaller increments indicative of shorter time positioned therebetween. The rotative ring 18 has similar time indications with an arrow 24 at the zero or start time. The rotative ring 18 being indicative of a start time is moved until the arrow aligns with the actual time that the container 14 was filled. When a user 12 wishes to determine the length of time expired since the container 14 was filled, the user obtains the actual time from a watch or clock and refers to a position on the stationary ring 16 correlating to the obtained time whereupon reference is made to the rotative ring 18 at the point opposing the stationary ring 16 which discloses an elapsed time period since the container's 14 contents were prepared.
