To UTC

Use toUtc() to convert any supported temporal type to a java.time.Instant and write it back to the field.

import static dev.ditsche.teki.rule.builder.Rules.*;

Teki schema = Teki.fromRules(
    temporal("publishedAt").required().toUtc(),
    temporal("updatedAt").toUtc()
);

All timezone and offset information is applied before the conversion, so the resulting Instant represents the same point in time as the original value.

Input types

toUtc() accepts any temporal type that temporal() recognizes:

• java.time.Instant — passed through unchanged
• java.time.ZonedDateTime — offset applied, converted to Instant
• java.time.OffsetDateTime — offset applied, converted to Instant
• java.time.LocalDateTime — interpreted in the JVM default timezone, then converted
• java.time.LocalDate — start of day in the JVM default timezone, then converted
• java.util.Date — converted directly
• java.util.Calendar — converted directly
