read-only
minute → Expression<int>: Extracts the minute from this datetime expression.
read-only
month → Expression<int>: Extracts the month from this datetime expression.
read-only
second → Expression<int>: Extracts the second from this datetime expression.
read-only
secondsSinceEpoch → Expression<int>: Returns an expression containing the amount of seconds from the unix epoch (January 1st, 1970) to this datetime expression.
read-only
time → Expression<String>: Formats this datetime in the format hour:minute:second.
read-only

The format string supports the most common substitutions found in the strftime() function from the standard C library plus two new substitutions, %f and %J. The following is a complete list of valid strftime() substitutions:

operator +(Duration duration) → Expression<DateTime>: Adds a duration to this date.
operator -(Duration duration) → Expression<DateTime>: Subtracts duration from this date.

fromUnixEpoch(Expression<int> unixEpoch) → Expression<DateTime>: Converts a numeric expression unixEpoch into a date time by interpreting it as the amount of seconds since 1970-01-01 00:00:00 UTC.
