A time indicator that rapidly changes color after a specific time interval is provided. The time indicator includes a base substrate with colored dye deposited on a first surface; a barrier applied over the colored dye; and a substrate having an adhesive on a first surface thereof. The substrate and the base substrate are put into adhesive contact. The adhesive coacts with the barrier to dissolve the barrier in a specified time interval. The adhesive then contacts the colored dye to dissolve the dye and permit the dye to migrate through the adhesive to cause a color change visible through the substrate.
