Default timezone for date handling
Formatter which formats a universal time for output as a date and time
Modifiers:
- os: an output stream designator
- arg: a universal time
- colon-p: a generalised boolean (default false).
If true use month and day names in date
- at-p: a generalised boolean (default false) - if true print in yyyy-mm-dd
(sortable) format rather than dd-mm-yyy
- precision: what precision to print it to. 6 is to the second,
7 includes timezone, a negative number counts backward.
- timezone: an integer (default nil).
If nil no timezone used and time is in current timezone
adjusted for daylight saving time.
Result:
nil
Examples:
(format nil "~/date/" (get-universal-time)) => "19-03-2009 08:30"
Formatter which outputs its numerical argument ‘arg‘ in engineering format
to stream ‘os‘.
It takes arguments d,padchar,exponentchar where
d is the number of decimal places to display after the decimal point
padchar is the character to pad the start of the number
exponentchar is the character to use to display between radix and exponent
It also takes the : modifier which will cause it to output the exponent
as an SI units prefix rather than a number.
Arguments:
- ‘os‘: an output stream designator
- ‘arg‘: a number
- ‘colon-p‘: a generalised boolean (default false)
- ‘at-p‘: a generalised boolean (default false) - if set right align field
- ‘d‘: an integer (default 2)
- ‘padchar‘: a character (default ‘space‘)
- ‘exponentchar‘: a character (default ‘e‘))
Result:
nil
Examples:
‘(format nil "~/eng/" 35000) => "35.00e+3"‘
Return a new string by joining together the STRINGS, separating each string with a SEPARATOR character or string
Parse a string of whitespace delimited arguments according to spec.
The specification is a list of entries each
of which lists the name, and optionally type and default values. The
output is an alist of variable names and parsed values.
If allow-spaces is true, last element can contain spaces
Parse an option list (alist of names and strings to be parsed) against a specification. The specification is a list of entries each of which lists the name, and optionally type and default values. The output is an alist of variable names and parsed values. Options in options-list not in spec are not returned and will signal an error unless allow-other-options is true
Split ‘string’ along whitespace as defined by the sequence ‘ws’. Whitespace which causes a split is elided from the result. The whole string will be split, unless ‘max’ is provided, in which case the string will be split into ‘max’ tokens at most, the last one containing the whole rest of the given ‘string’, if any.
Returns true if the parsed value input is
equivalent (equals) the reference value according to the stype
specification. If specification is a list the first element specifies
the actual validation method and the rest of the list are passed as
keyword arguments to the specific method.

specification, returning the validated object. Throws an invalid-format
condition if input is invalid. If specification is a list the first
element specifies the actual validation method and the rest of the
list are passed as keyword arguments to the specific method e.g.
(parse-input ’(integer :min 0) input)
will return the integer value from string if it is >0, or signal and
invalid-format condition if not.
(parse-input ’(member :type integer :set (1 5 7)) input)
will return it only if it has a value in the set.
The use-value restart may be used to provide substitute value if the input is invalid.

Formats a universal time for output.
OUT controls where the result will go. If OUT is T, then the output
is sent to the standard output stream. If it is NIL, then the output
is returned in a string as the value of the call. Otherwise, OUT must
be a stream to which the output will be sent.
UTIME is the universal time to be output (default is current time)
TZ is the time zone default will give local time.
FMT is a keyword symbol specifying which output format is used as follows
:RFC2822 - output as per RFC2822 for internet messages
:SHORT - output in a shorter format (same as :ISO)
:TIME-ONLY - outputs time as hh:mm:ss
:DATE-ONLY - outputs date as dd-mm-yyyy
:ISO - output as per ISO 8602
Given a string, and start, end, and radix parameters, produce a number according to the syntax definitions in the Common Lisp Hyperspec.
Given a string, and start, end, and radix parameters, produce a number according to the syntax definitions in the Common Lisp Hyperspec – except for complex numbers and negative numbers.
Given a string, and start, end, and radix parameters, produce a number according to the syntax definitions in the Common Lisp Hyperspec – except for complex numbers.
Tries very hard to make sense out of the argument time-string and returns a single integer representing the universal time if successful. If not, it returns nil. If the :error-on-mismatch keyword is true, parse-time will signal an error instead of returning nil. Default values for each part of the time/date can be specified by the appropriate :default- keyword. These keywords can be given a numeric value or the keyword :current to set them to the current value. The default-default values are 00:00:00 on the current date, current time-zone.
