The datetime, date, and time types.
Internet Object has three temporal types, each with its own literal value:
date
d'2024-03-20'
calendar date
time
t'14:30:45'
time of day
datetime
dt'2024-03-20T14:30:45Z'
date + time (ISO 8601)
For the literal value syntax in detail, see Date and Time.

datetime, date, or time. First positional value.

Restricts the value to a fixed set.
min
datetime
Earliest allowed value (inclusive).
max
datetime
Latest allowed value (inclusive).
optional
bool
If true, the member may be omitted. Shorthand: ? suffix.

valid temporal literal
the value
out of min/max
invalid-range error
N, nullable (*)
null
N, not nullable
null-not-allowed error
omitted, optional (?)
absent
omitted, required
value-required error
datetime currently drops the seconds component on parse (dt'…T14:30:45Z' is read as …14:30:00). Under review.
Keyed null: is not yet honored — use the * suffix.
