timezone (tz) - English Language Timezone Conversion
The source code can be found at this GitHub repo. When the source has been obtained the easiest way to compile is with cargo build --release, then add path/to/timezone/target/release to your PATH. I do not know if this software compiles on Windows, if you have any problems with doing this open an issue.
This software is distributed also at crates.io, and should be able to be installed with cargo install timezone.
It should be possible to use this software in other rust programs with cargo add timezone. The majority of the actual conversion logic is handled by chrono-tz, but src/parse.rs provides several methods for parsing English-language inputs, which may be useful for you.
tz time origin_timezone destination_timezone day month year
For example:
tz 1pm et bst tomorrow
will tell you what 1pm eastern US time is in British summer time tomorrow.
time should be in one of the following formats:
| Format | Examples |
|---|---|
| SimpleAmPm | 1am, 10pm |
| FullAmPm | 12:24am, 6:30pm |
| MilitaryColon | 07:00, 13:52 |
| Military | 0900, 1634 |
The timezones can be either a city, such as Europe/London, America/Los_Angeles, or even US/Eastern; or a timezone abbreviation, such as gmt, est, aet. A full list of available abbreviations can be found by consulting src/convert_timezones.rs.
day, month, and year are for the most part self-explanatory, but you can also specify today, tomorrow or yesterday for the day.
This software is robust, you do not have to fully-specify the conversion that you want to perform. At a minimum you can specify only the time and the origin, with the rest being assumed to be your local timezone, the current day, the current month, and the current year.
