Useful tools when working with Unicode files when one doesn't know the writing system, doesn't have the necessary font, needs to inspect invisible characters, needs to find out whether characters have been combined or in what order they occur, or needs statistics on which characters occur.

• uniname defaults to printing the character offset of each character, its byte offset, its hex code value, its encoding, the glyph itself, and its name. It may also be used to validate UTF-8 input.

• unidesc reports the character ranges to which different portions of the text belong. It can also be used to identify Unicode encodings (e.g. UTF-16be) flagged by magic numbers.

• unihist generates a histogram of the characters in its input.

• ExplicateUTF8 is intended for debugging or for learning about Unicode. It determines and explains the validity of a sequence of bytes as a UTF8 encoding.

• utf8lookup provides a handy way to look up Unicode characters from the command line.

• unireverse reverse each line of UTF-8 input character-by-character.

Miller (mlr) is like awk, sed, cut, join, and sort for data formats such as CSV, TSV, JSON, JSON Lines, and positionally-indexed. It supports format conversion and pretty-printing.

ack is a tool for finding text inside files. It is designed for hackers and programmers by being fast, ignoring VCS directories, letting a user easily specify file types, match highlighting, Perl-Compatible Regular Expressions, and being faster to type than grep.

This library provides a timezone database for Python.

This package contains a library for parsing ISO 8601 datetime strings.

This package includes the necessary headers for using LinuxPPS PPSAPI kernel interface in user-space applications, and several support tools.

Utility that fakes the system time by pre-loading a small library that modifies the time, gettimeofday and clock_gettime system calls.

This library brings the Olson tz database into Python. It allows accurate and cross platform timezone calculations using Python 2.4 or higher. It also solves the issue of ambiguous times at the end of daylight saving time. Almost all of the Olson timezones are supported.

This package provides functionality for utilizing the relativedelta feature from the dateutil library, ensuring calendar precision with aniso8601.

Arrow is a Python library to creating, manipulating, formatting and converting dates, times, and timestamps. It implements and updates the datetime type.

This module parses the most common forms of ISO 8601 date strings (e.g. 2007-01-14T20:34:22+00:00) into datetime objects.

Termdown provides a fancy text display while it counts down to zero from a starting point you provide. The user can pause and resume the countdown from the text user interface. It can also be used in stop watch mode which counts forward or for just showing the current time.

Time is a command that displays information about the resources that a program uses. The display output of the program can be customized or saved to a file.

rdate connects to an RFC 868 time server over a TCP/IP network, printing the returned time and/or setting the system clock.

The package ciso8601 converts ISO 8601 or RFC 3339 date time strings into Python datetime objects.

tz helps you schedule things across time zones. It is an interactive TUI program that displays time across a few time zones of your choosing.

The strict_rfc3339 Python module provides strict, simple, lightweight RFC3339 (Date and Time on the Internet: Timestamps) procedures.

It enables or aims to:

• Convert UNIX timestamps to and from RFC3339.

• Produce RFC3339 strings with a UTC offset (Z) or with the offset that the C time module reports is the local timezone offset.

• Be simple with minimal dependencies/libraries.

• Avoid timezones as much as possible.

• Be very strict and follow RFC3339.

This package provides a thin Python wrapper around tzdata.

This module provides a monotonic() function which returns the value (in fractional seconds) of a clock which never goes backwards.

This small Python module parses various kinds of time expressions.

Python library for generating and parsing RFC 3339-compliant timestamps.

Countdown provides a fancy text display while it counts down to zero from a starting point you provide. The user can pause and resume the countdown from the text user interface.

Python-isodate is a python module for parsing and formatting ISO 8601 dates, time and duration.

The main purpose of this package is to provide more complex arithmetic operations on dates/times. Heavy use is made of the relativedelta type from the dateutil library. Much of this package is just a light wrapper on top of this with some added features such as range generation and business day calculation.
