δt

A CLI that allows you to convert time from one time zone to another.

dt supports the following timezones

• wast: West African Standard Time
• et: Easter Time
• pt: Pacific Time
• ct: Central Time
• at: Atlantic Time
• ist: Indian Standard Tim

How it works

To convert from West African Standard Time to Indian Standard Time, you can use the command:

dt 10:30 wast ist

Adding a timezone

Supported timezones and conversion values are hard-coded in the program and not read from an external source. The timezones reside in a StringHashMap, akin to a dict in python or object in JavaScript.

try map.put("wast", 1);
try map.put("et", -4);
try map.put("pt", -7);
try map.put("ct", -5);
try map.put("at", -4);
try map.put("ist", 5.5);

The whole number represents hours while the fractional part is a fraction of 1 hour. So 0.5 is 30 minutes.

Adding a timezone will require you to add a key-value pair where the value is the time difference between the timezone and GMT.
