at the proper time
1Proper time — In relativity, proper time is time measured by a single clock between events that occur at the same place as the clock. It depends not only on the events but also on the motion of the clock between the events. An accelerated clock will measure a… …
2Time dilation — This article is about a concept in physics. For the concept in sociology, see time displacement. In the theory of relativity, time dilation is an observed difference of elapsed time between two events as measured by observers either moving… …
3Proper length — In relativistic physics, proper length is an invariant quantity which is the rod distance between spacelike events in a frame of reference in which the events are simultaneous. (Unlike classical mechanics, simultaneity is relative in relativity.… …

6Proper motion — The proper motion of a star is its angular change in position over time as seen from the center of mass of the solar system.[1] It is measured in seconds of arc per year, arcsec/yr, where 3600 arcseconds equal one degree.[2] This contrasts with… …

8The Gathering (computer party) — The Gathering (abbreviated as TG for short) is one of the largest computer parties in the world. It is held annually in Vikingskipet Olympic Arena in Hamar, Norway, and lasts for five consecutive days (starting on the Wednesday in Easter each… …
9Time value of money — The time value of money is the value of money figuring in a given amount of interest earned over a given amount of time. The time value of money is the central concept in finance theory. For example, $100 of today s money invested for one year… …
