Method Details

truncatedToMicros

public static LocalDateTime truncatedToMicros(LocalDateTime value)

Truncate the time part of a LocalDateTime to microseconds.

In Java 17 the resolution of time objects increased from microseconds to nanoseconds. Java always stored a time with nanosecond precision but the last three digits have been zero. With the increase of resolution we are facing trouble with the persistence layer: most databases only support microseconds, so does ours. As a consequence the original object and the one retrieved from the database are different -- they differ in 1000 nanoseconds. To overcome this inconsistency the time values must be truncated to microseconds, the resolution that the database can store.

Parameters:

value -

Returns:

the LocalDateTime truncated to microseconds
