gmtime/localtime (time.h functions) work incorrectly in CCSv6

tml

Hi,

I just found out that the gmtime and localtime produce incorrect date based on the time_t value. The 1404337303 value stands for Wed Jul 2 21:41:43 2014.

The following code snippet:

time_t rawtime = 1404337303;
struct tm * timeinfo;
timeinfo = gmtime(&rawtime);
printf("===Current local time and date: %s", asctime(timeinfo));

produces incorrect date output in CCSv6:

===Current local time and date: Mon Jul  3 03:41:43 1944

while in the GCC it is:

==Current local time and date: Wed Jul  2 21:41:43 2014

Is there any workaround on this apart from not using time.h?

Best Regards,

tml

Please see the discussion of the epoch in this wiki article about the time and clock functions.

Thanks and regards,

IIRC (from a different thread), the CCS library doesn’t support timezones. Instead, as posted, it uses a different base tiem ('epoch' that corresponds to UTC-6.
So "UTC" and localtime are the same if you life at UTC-6. But if you have a different localtime, things start to get confusing. And of course the linux tiem value differs form the TI one by 6 hrs.

Hi,

Has someone found a workaround for this? gmtime (time.h) does not work properly in CCSv6.

Thanks and best Regards,

David

TI has no collateral other than the wiki article already mentioned.

Thanks and regards,
