  2. List of time zone abbreviations - Wikipedia

    en.wikipedia.org/wiki/List_of_time_zone...

    Such designations can be ambiguous; for example, "CST" can mean China Standard Time (UTC+08:00), Cuba Standard Time (UTC−05:00), and (North American) Central Standard Time (UTC−06:00), and it is also a widely used variant of ACST (Australian Central Standard Time, UTC+9:30). Such designations predate both ISO 8601 and the internet era; in ...

  3. KST oscillator - Wikipedia

    en.wikipedia.org/wiki/KST_oscillator

    KST can be interpreted in the ways mentioned below. [6] The dominant time frame in the Know Sure Thing (KST)'s construction is a 24-month period, which is half of the 4-year business cycle. This means that the Know Sure Thing (KST) will work best when the security in question is experiencing a primary up- and downtrend based on the business cycle.

  4. List of tz database time zones - Wikipedia

    en.wikipedia.org/wiki/List_of_tz_database_time_zones

    Standard Time (SDT) and Daylight Saving Time (DST) offsets from UTC in hours and minutes. For zones in which Daylight Saving is not observed, the DST offset shown in this table is a simple duplication of the SDT offset.

  5. List of UTC offsets - Wikipedia

    en.wikipedia.org/wiki/List_of_UTC_offsets

    This is a list of the UTC time offsets, showing the difference in hours and minutes from Coordinated Universal Time (UTC), from the westernmost (−12:00) to the easternmost (+14:00). It includes countries and regions that observe them during standard time or year-round.

    Microsoft Excel is a spreadsheet editor developed by Microsoft for Windows, macOS, Android, iOS and iPadOS.It features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA).

  7. Effects of time zones on North American broadcasting

    en.wikipedia.org/wiki/Effects_of_time_zones_on...

    Local programming such as locally produced newscasts are not typically affected as many stations air their morning newscast at 4:00, 4:30, 5:00 or 5:30 a.m., and their early evening newscasts at 5:00 and/or 6:00 p.m.; however, the late evening newscast is affected due to the differences in time between time zones, meaning that if the late local ...

  8. Newton polynomial - Wikipedia

    en.wikipedia.org/wiki/Newton_polynomial

    The divided difference formulas are more versatile, useful in more kinds of problems. The Lagrange formula is at its best when all the interpolation will be done at one x value, with only the data points' y values varying from one problem to another, and when it is known, from past experience, how many terms are needed for sufficient accuracy.

  9. Backward differentiation formula - Wikipedia

    en.wikipedia.org/wiki/Backward_differentiation...

    The backward differentiation formula (BDF) is a family of implicit methods for the numerical integration of ordinary differential equations.They are linear multistep methods that, for a given function and time, approximate the derivative of that function using information from already computed time points, thereby increasing the accuracy of the approximation.
