Overview
Dates are immutable objects that represent calendar dates and times.
Operations
create = proc (day, month, year, hour, minute, second: int) returns (date) signals (bad format)
e ects Creates the speci ed date. The ranges for the arguments
are |
(1 .. |
31), (1 12), (1 ), (0 23), (0 59), (0 59),.. .. .. .. .. |
||
respectively |
bad |
|
format is signaled if an argument is out of |
|
|
||||
range. |

get all = proc (d: date) returns (int, int, int, int, int, int)
e ects Returns the components in the same order as given to create.
get day = proc (d: date) returns (int) get month = proc (d: date) returns (int) get year = proc (d: date) returns (int) get hour = proc (d: date) returns (int) get minute = proc (d: date) returns (int) get second = proc (d: date) returns (int)
e ects Returns the speci ed component of d.
unparse = proc (d: date) returns (string)
e ects Returns a string representation of d|for example, \12 January 1978 01:36:59".
unparse date = proc (d: date) returns (string)
e ects Returns a string representation of the date part of d|for example, \12 January 1978".
unparse time = proc (d: date) returns (string)
e ects Returns a string representation of the time part of d|for example, \01:36:59".
lt = proc (d1, d2: date) returns (bool)) le = proc (d1, d2: date) returns (bool) ge = proc (d1, d2: date) returns (bool) gt = proc (d1, d2: date) returns (bool)
equal = proc (d1, d2: date) returns (bool) e ects The obvious relational operations
if d1 < d2 , then d1 occurs earlier than d2.
similar = proc (d1, d2: date) returns (bool) e ects The same as the equal operation.
copy = proc (d: date) returns (date) e ects Returns a date equal to d.
end date
