Time study
A time study is a work measurement procedure determining how long a qualified, trained operator needs to perform a task, first developed by Frederick W. Taylor.
Time synchronization
Time synchronization aligns the clocks of separate computers or devices to a common time reference over a network, typically via the Network Time Protocol (NTP).
Time Team
Time Team, British Channel 4 archaeology series (1994-2013) created by Tim Taylor and presented by Tony Robinson; three-day digs, 20 series, over 230 episodes, £4m invested, revived 2021 on YouTube via Patreon.
Time to Hunt (사냥의 시간) (film)
Time to Hunt (사냥의 시간) is Yoon Sung-hyun's 2020 Korean dystopian heist thriller starring Lee Je-hoon, Choi Woo-sik, and Park Hae-soo; a Berlinale Special Gala film that skipped theaters for Netflix after a COVID-19 delay and a court injunction over overseas sales rights.
Time to Interactive
Time to Interactive (TTI) is a web performance metric measuring the time from page load until the page reliably responds to input, developed for Lighthouse and removed as a scored metric in Lighthouse 10.
Time to Leave
Time to Leave (Le Temps qui reste) is François Ozon's 2005 French drama, in Un Certain Regard at Cannes, about Romain, a 30-year-old photographer with terminal cancer, starring Melvil Poupaud, Jeanne Moreau, and Valeria Bruni Tedeschi.
Time to live
Time to live (TTL), called Hop Limit in IPv6, is an IP header field limiting a packet's lifetime, decremented by each router until zero, when the packet is discarded.
Time trade-off
The time trade-off is a health economics survey method that values a health state by how much life expectancy people would give up for full health.
Time Trap (film)
Time Trap (2017) is an American indie sci-fi adventure film directed by Mark Dennis and Ben Foster, about students trapped in a cave where time passes slowly; premiered at SIFF 2017, released by Paladin in 2018, distinct from the 1964 film of the same title.
Time travel
Time travel, also known as temporal displacement, is movement between different points in time. Travel to the future is confirmed by relativity; travel to the past remains hypothetical.
Time travel claims and urban legends
Time travel claims and urban legends: John Titor (TimeTravel_0) and the Philadelphia Experiment. Forum-hoax and folklore cases versus real relativistic time dilation; no verified future visitor found.
Time travel in fiction
Time travel in fiction: the science fiction subgenre and narrative device begun with H.G. Wells's The Time Machine (1895), built on grandfather and bootstrap paradoxes, fixed timelines, and multiverse mechanisms.
Time value of money
The time value of money (TVM) is the finance principle that a dollar today is worth more than a dollar later, because money can earn a return.
Time Variance Authority
Time Variance Authority (TVA), Marvel Comics fictional bureaucracy monitoring multiverse timelines from the Null-Time Zone; created by Walt Simonson and Sal Buscema in Thor #372 (1986), later central to the MCU's Loki and its own 2024 comic series.
Time War (Doctor Who)
The Last Great Time War is Doctor Who's off-screen war between the Time Lords and Daleks, created for the 2005 revival; the Doctor ended it with the Moment, a Time Lock sealed it, and The Day of the Doctor later revealed Gallifrey survived.
Time Warner Cable
Time Warner Cable was an American cable and broadband company formed in 1992 from Time Inc.'s and Warner Communications' cable arms, acquired by Charter Communications in 2016.
Time Warp Mexico 2026
Time Warp Mexico 2026 is the Mexican edition of the German techno festival Time Warp, held 20–21 November 2026 at Expo Santa Fe in Mexico City.
Time Warp NYC
Time Warp NYC is the New York edition of the German techno festival Time Warp, staged by Cosmopop in Brooklyn since 2014 and running annually since 2023.
Time Without Pity
Time Without Pity is a 1957 British thriller directed by Joseph Losey, his first film under his own name after the Hollywood blacklist, adapted from Emlyn Williams' play Someone Waiting, starring Michael Redgrave as a father with 24 hours to save his son from hanging.
Time zone
A time zone, also called a local time, is a region whose inhabitants keep a common local time, usually a whole number of hours from UTC.
Time-based metering
Time-based metering is an air traffic management method that assigns each aircraft a scheduled time to cross a constraint point, sequencing traffic by time instead of distance.
Time-bin encoding
Time-bin encoding represents quantum information in a single photon placed in a superposition of two time slots separated by a fixed delay, used in quantum key distribution.
Time-correlated single photon counting
Time-correlated single photon counting (TCSPC) is a spectroscopy technique that measures fluorescence lifetimes by timing individual photons against a pulsed excitation source, building a histogram over many pulses.
Time-crystalline eigenstate order
Time-crystalline eigenstate order is a form of quantum order in Floquet systems where the entire many-body spectrum carries long-range order, underlying the many-body-localized discrete time crystal.
Time-delay cosmography
Time-delay cosmography measures the Hubble constant from time delays between gravitationally lensed images of variable sources like quasars, an idea proposed by Søren Refsdal in 1964.
Time-delay integration
Time-delay integration, or drift scanning, is a CCD readout mode where charge shifts across the sensor to match the sky's drift, enabling continuous survey scans.
Time-dependent density functional theory
Time-dependent density functional theory (TDDFT) is a quantum-mechanical method that computes excited states and optical response of atoms, molecules, and materials from the electron density.
Time-dependent dielectric breakdown
Time-dependent dielectric breakdown (TDDB) is a failure mechanism in which a dielectric such as a MOS transistor's gate oxide degrades under sustained electric field until traps form a conducting path.
Time-dependent diffusion MRI
Time-dependent diffusion MRI (TDDMRI or TDD-MRI) is a diffusion MRI technique that varies diffusion time to map microstructure like cell size and density, used mainly in oncology.
Time-dependent inhibition
Time-dependent inhibition, also called slow-onset or slow-binding inhibition, is enzyme inhibition that takes seconds to minutes to reach full effect, seen as curved reaction progress curves.
