Dates

Jitzu has three temporal types: Date for calendar dates, Time for times of day, and Timestamp for a combined date and time.

Date

Jitzu

// Parse a date from a string
let date = try Date.parse("2024-01-15")
print(date)  // 2024-01-15

// Compare dates
let start = try Date.parse("2024-01-01")
let end = try Date.parse("2024-12-31")
print(start == end)   // false
print(start < end)    // true

Time

Jitzu

// Parse a time from a string
let time = try Time.parse("14:30:00")
print(time)  // 14:30:00

// Compare times
let morning = try Time.parse("08:00:00")
let evening = try Time.parse("20:00:00")
print(morning < evening)  // true

Timestamp (Date + Time)

Combine a Date and Time to create a Timestamp, or parse one directly:

Jitzu

// Combine date and time
let date = try Date.parse("2024-01-15")
let time = try Time.parse("12:00:00")
let timestamp = date + time
print(timestamp)  // 2024-01-15 12:00:00

// Parse a timestamp directly
let ts = try Timestamp.parse("2024-01-15 12:00:00")

// They compare equal
print(timestamp == ts)  // true

Error Handling

Parsing returns a Result, so invalid input is handled safely:

Jitzu

let result = Date.parse("not-a-date")
match result {
  Ok(d) => print(d),
  Err(e) => print(`Parse error: {e}`),
}
