Unix Timestamp in Scala
Use `java.time.Instant` - Scala uses the Java date/time API directly.
Common Operations
Get current Unix timestamp
val ts = java.time.Instant.now().getEpochSecond // 1706745600
Convert Unix timestamp to Instant
val instant = java.time.Instant.ofEpochSecond(1706745600)
Format as ISO 8601
java.time.Instant.now().toString // '2024-01-31T22:40:00.123Z'
