From f62b1f5500a183495e1e80d1485d2a783a37c2b2 Mon Sep 17 00:00:00 2001 From: tradke Date: Fri, 28 Jul 2006 09:57:00 +0000 Subject: Add new flesh API functions CCTK_CompileDateTime() and Util_CurrentDateTime() to return a date/time stamp following the ISO 8601 standard format if possible (see http://www.cactuscode.org/old/pipermail/developers/2006-July/004971.html). Add the timezone information in the time stamp returned by Util_CurrentTime(). You also need to update lib/make/make.configuration now in order to compile src/datestamp.c. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4358 17b73243-c579-4c4c-a9d2-2d5706c11dac --- src/datestamp.c | 47 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) (limited to 'src/datestamp.c') diff --git a/src/datestamp.c b/src/datestamp.c index bc73cfd3..7f0dd7b8 100644 --- a/src/datestamp.c +++ b/src/datestamp.c @@ -8,6 +8,7 @@ #version $Id$ @@*/ +#include #include #include @@ -92,6 +93,52 @@ const char *CCTK_CompileDate (void) #define REALSTRINGIFY(a) #a + /*@@ + @routine CCTK_CompileDateTime + @date 21 July 2006 + @author Thomas Radke + @desc + Returns a pointer to a formatted string with the datetime stamp + when Cactus was compiled. + The format of the string returned tries to be compatible + to the machine-processable format defined in ISO 8601 chapt. 5.4 + however this depends on the actual date command which returns + the raw datetime string CCTK_COMPILE_DATETIME + in lib/make/make.configuration. + @enddesc + + @returntype const char * + @returndesc + pointer to the static datetime stamp string buffer + @endreturndesc +@@*/ +const char *CCTK_CompileDateTime (void) +{ +#define DATETIME_BUFLEN sizeof("YYYY-MM-DDThh:mm:ss+hh:mm") + const int len = DATETIME_BUFLEN; + static char buffer[DATETIME_BUFLEN] = ""; + + if (buffer[0] == 0 && sizeof (STRINGIFY (CCTK_COMPILE_DATETIME)) == len-1) + { + strcpy (buffer, STRINGIFY (CCTK_COMPILE_DATETIME)); + + /* if the timezone part is returned as "(+|-)hhmm" + then turn it into "(+|-)hh:mm" */ + if ((buffer[len-7] == '+' || buffer[len-7] == '-') && + isdigit (buffer[len-6]) && isdigit (buffer[len-5]) && + isdigit (buffer[len-4]) && isdigit (buffer[len-3]) && + buffer[len-2] == 0) + { + buffer[len-2] = buffer[len-3]; + buffer[len-3] = buffer[len-4]; + buffer[len-4] = ':'; + } + } + + return (buffer[0] ? buffer : STRINGIFY (CCTK_COMPILE_DATETIME)); +} + + /*@@ @routine CCTK_FullVersion CCTK_MajorVersion CCTK_MinorVersion @date Mon May 11 10:20:58 1998 -- cgit v1.2.3
