# What is monotonic time?

doc.aldebaran.comImage: doc.aldebaran.comIf you’re a calculus expert, you may even yell at me and I’ll take it, but for the purposes of this article, we can say that a monotonic time is a time where we want to ensure that the difference between the begin and end of a given routine is perfectly measured in a unity that is constantly moving forward tick by tick.

## What is a monotonic clock?

A monotonic clock is a clock that can not go backward. As the reference point of the returned value of the monotonic clock is undefined, only the difference between the results of consecutive calls is valid. Parameter: No parameter is required.

## What is monotonic time source?

Time::Monotonic gives access to monotonic clocks on various platforms (Mac OS X, Windows, and POSIX). A monotonic clock is a time source that won’t ever jump forward or backward (due to NTP or Daylight Savings Time updates).

## What is a monotonic function?

I’ll define a monotonic function as a subset of constant values. The values are strictly increasing or decreasing, not jumping back/forward.

## What is time::monotonic?

Time::Monotonic gives access to monotonic clocks on various platforms (Mac OS X, Windows, and POSIX). A monotonic clock is a time source that won’t ever jump forward or backward (due to NTP or Daylight Savings Time updates). Time::Monotonic uses Thomas Habets’s cross platform “monotonic_clock” library under the hood.

### 1. When to use Monotonic Time | Sourcetoad

Oct 03, 2016 · Unlike a UTC timestamp (which starts January 1st, 1970), Monotonic time starts at an arbitrary point. It cannot move backwards. Finally, and most importantly, it is completely independent of the system clock: changes to the system clock will not affect a monotonic time. Using a monotonic time for our callback resolved the issue, but this is a very special use-case. …

### 2. Python | time.monotonic() method – GeeksforGeeks

Aug 21, 2019 · Last Updated : 08 Oct, 2021 Python time.monotonic () method is used to get the value of a monotonic clock. A monotonic clock is a clock that can not go backward. As the reference point of the returned value of the monotonic clock is undefined, only the difference between the results of consecutive calls is valid.

### 5. Precise timings with `monotonic_time` – Today I Learned

Monotonic time is time from a clock that only moves forward. The system clock on your CPU can be set and reset. Even when tied to the LAN ntp protocol the system clock can be out-of-sync by a couple of milliseconds. When measuring in microseconds, that’s a lot of time, and time drift can occur at the microsecond level even when attached to …

### 6. GLib.get_monotonic_time

The monotonic clock will always increase and doesn’t suffer discontinuities when the user (or NTP) changes the system time. It may or may not continue to tick during times where the machine is suspended. We try to use the clock that corresponds as closely as possible to the passage of time as measured by system calls such as poll () but it …
