[REBOL] unix timestamp conversion?

[REBOL] Mail
Hello all... I'm having this problem: I can access my e-mail server without a proxy server, but if i try to access it with the "help" of my proxy server then i can't reach it (it is not the objective of the proxy server). But if I want to access web pages, the only way to do that is using the proxy server. My problem is that when we configure the proxy server in REBOL he assumes that the proxy should be used also to access the mail server. Is there a way to correct this excluding the hipothesis of doing a set-net every time i want to access the web or the mail?! -- Signout: Zé Matos -- A frase imediatamente abaixo desta é verdadeira!

Hi Francois:
Try this.
REBOL [
Title: "Convert Epoch Time to Date"
Author: "Ralph Roberts"
File: %epoch-to-date.r
Date: 21-Feb-2000
Purpose: {converts UNIX Epoch time (seconds after 1-1-1970
to current date and time }
Example: {outputs "Epoch date 951142987 is 21-Feb-2000
14:38:52 GMT or 9:38:52 Local" }
]
epoch: 951142987
days: divide epoch 86400
days2: make integer! days
time: (days - days2) * 24
hours: make integer! time
minutes: (time - hours) * 100
minutes2: make integer! minutes
seconds: make integer! (minutes - minutes2) * 100
time2: make time! hours * 60) + minutes2) * 60) + seconds)
prin ["Epoch date" epoch "is" 1-Jan-1970 + days2 time2]
print [" GMT or" time2 + now/zone "Local"]

Cheers Francois And to do it the other way around, i.e. generate an Epoch date: REBOL[ ] date: now seconds: ((date - 1-1-1970) * 86400) + (date/time/hour * 3600) + (date/time/minute * 60) + date/time/second zone: now/zone zone: zone/hour zone: zone * 3600 seconds: seconds - zone ; minus a minus gives plus print seconds ; Epoch date
[REBOL] .r to html monthly calendar prelude Re:(4)
I've loaded well over 100,000 records (about 100 char in length) via read/lines - probably more like 350,000. The biggest thing to watch out for is that REBOL will use about twice as much memory as the disk file size to store it in a block. - Michael Jelinek -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Sunday, February 20, 2000 8:01 AM To: [EMAIL PROTECTED] Subject: [REBOL] .r to html monthly calendar prelude Re:(3) REBOL is perfect for storing a wide range of data values, so can be used for creating databases up to and beyond several thousand records. This is useful Does any one know what the true limit is? I've got a data base of 23,000 records right now, growing at a rate of about 100 entries per week.
[REBOL] constructor destructor Re:
I create a "wrapper" function around the make object! declaration to create an instance of the "class", then call this wrapper function explicitly when I want a new instance. This wrapper function does the initialization and such of a constructor. If you cared, you could also write a function for the destructor, and call it explicitly. Alas, these are not "true oo" constructors and destructors as they are not elements of the object, but they work. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Monday, February 21, 2000 4:17 AM To: [EMAIL PROTECTED] Subject: [REBOL] constructor destructor Since I've programmed sometime i C++ with classes (almost like objects in REBOL), I've missed some features in the objects in REBOL.

Hello [EMAIL PROTECTED]! On 20-Feb-00, you wrote: s tmp: load system/options/cgi/content-length s buffer: make string! (tmp + 10) s read-io system/ports/input buffer tmp AFAIK this could not read all the data. I think it's better to use something like: while [tmp 0] [tmp: tmp - read-io system/ports/input buffer tmp] s system/options/cgi/content-length but it is quaranteed that s content-length will be send everytime by each browser (or s another user-agent)? (question for Holger?) The browser MUST include the Content-Length header if it is sending data. If it doesn't, the server cannot tell how much data to wait for. s what about reading stdin by this way: s instr: make string! 5 * 1024 while [found? tmp: pick s system/ports/input 1][append instr tmp] Rather slow IMHO... and it will not work in case of binary data (well, that shouldn't be your case anyway).

[REBOL] using environment variables Re:(2)
Hi Robert, Danke! I must have missed your answer before... Well, setting environment variables would have been what I really need. Does anybody else know if it's possible? Tom P.S.: If Rebol can't do this, any suggestions for another language that provides an easy way to set environment variables? [EMAIL PROTECTED] wrote: does anyone know if or how it's possible to use (get and SET) OS environment variables from within Rebol? Hi, I think if you start Rebol in CGI mode, you will get the environment... setting variables isn't possible AFAIK.
[REBOL] constructor destructor Re:(2)
Hi Martin, re: destructors: Note that REBOL has automatic garbage collection. This means that the memory that was allocated by an object programmatically during its creation processor or subsequently will be automatically released when the object is destroyed. In contrast, programming languages like C++ that do not have automatic garbage collection require a destructor function, so that you will be able to clean up, i.e. release programmatically allocated memory, when your object is destroyed. With automatic garbage collection, i.e. memory getting automatically reclaimed, I think the motivation behind a destructor function no longer exists and a destructor function is no longer critical. ;- Elan [: - )]

REBOL [ Title: "HTML Monthly

Purpose:

Prelude to AN INTERACTIVE HTML MONTHLY CALENDAR.
Currently, using the Rebol Console, you enter
themonth and year you are interested in.This
code prints the html version of that month to a file called

Comment: { Thanks to bpaddock, olivier
doleman, Donald Dalley, karin,
rryost especially Olivier doleman
for the slick date coding, and Donald Dalleyand others on list who
replied to my initial 'prelude to HTML post'.
The next version
will be more interactive and completely cgi-enabled with a
database or series in flat
files. However...
I need HELP HERE: The simplist of code that is
intuitively obvious for veteran Rebols, is new to me.For
example. I've seen several html related scripts using an "EMIT"
function,yet I don't know how it works.
The ideal is to retrieve values from a database or at
least from a file, muchlike one using coldFusion, PERL, PHP, ASP etc.
However I've not found clear examples of dbase connection. Or
even less sophisticated examples of getting data from a flat
file. There are too few good examples ofusing REBOL words in the
dictionary. HELP !For example: What if I had a file with 365+
records many of which will conatinthe values of holidays and the like.
The unique key being the date.How do I get data from that file via
http? How would I write to that file for updates?How do I write
to that file to update the specific record only using cgi?
