ep
Simple date converter. Prints out the "date thing" converted to:
- An instant
- Epoch days
- Epoch millis
Usage
- From source:
clj -Arun <date-thing>
Or from an uberjar
- Build from source:
clj -Auberjar - Run
java -jar target/ep-1.0.0-standalone.jar <date-thing>
The "date thing" can be:
- A number of epoch days (any number less than 100000 is assumed to be epoch days).
- A number of epoch minutes (any number in the range 100000..10000000000 inclusive is assumed to be epoch minutes)
- A number of epoch millis (any number above 10000000000 is assumed to be epoch millis).
- A date or date/time string in ISO8601 form.
Epoch days
As they're referred to a lot less frequently than epoch millis, it's worth clarifying what is meant by "epoch days".
- The epoch days is the number of days since the Epoch start (i.e. 01/01/1970).
- So epoch days 0 = 01/01/1970, 1 = 02/01/1970 and so on.
- This means that when converting from a date thing representing a date/time, the epoch day is considered to be inclusive of all times on that day. So, for example,
1970-01-01T05:00:00Zand1970-01-01T23:59:59Zare both epoch day 0 but1970-01-02T00:00:00Zis epoch day 1.
