Most date and time types share code for data input. For those types (

.SH "TIMESTAMP"
This is currently a limited-range absolute time which closely resembles the
.IR abstime
data type. It shares the general input parser with the other date/time types.
In future releases this type will absorb the capabilities of the datetime type
and will move toward SQL92 compliance.
