Depending on your objective, you may be able to bypass ZoneOffset entirely.

Assuming you just need a ZoneOffset for e.g. LocalDateTime.ofEpochSecond(), you may replace

ZoneOffset offset = OffsetDateTime.now().getOffset();

with

LocalDateTime dt2 = LocalDateTime.ofInstant(
    Instant.ofEpochSecond(seconds), 
    ZoneId.systemDefault());

where dt1.equals(dt2) is true.
