How can I convert year, day, and minute to an Instant?

I have a table with columns containing an integer year, month of year, day of month, and minute of day. How can I convert these columns to a single Instant column?

Deephaven's query engine provides the necessary methods to convert integer year, month, day, and minute to an Instant in a given time zone.

from deephaven import empty_table

source = empty_table(1).update(["Year = 2024", "Month = 3", "Day = 4", "Minute = 720"])

result = source.update(
    [
        "Timestamp = LocalDate.of(Year, Month, Day).atTime(0, 0, 0).atZone('ET') + Minute * MINUTE"
    ]
)
