Are Date classes thread safe?

[mchalls]

I'm using Dateformatter like this:

Code: Select all

static std::string getTime() {
  Timestamp now;
  return DateTimeFormatter::format(LocalDateTime(DateTime(now)), "%Y-%m-%d %H:%M:%S.%i");
}


Sometimes I get segmentation fault within this function in a multithreaded application, on the return line when std::string is created. I'm suspecting that one of the Poco classes used above is not thread safe, but found no mention of this in the docs. Could you please advice?

I'm using Poco 1.3.6p2 on 64bit SLES11 SP1.

I can't find anything in any of the involved classes that would cause them to be non-reentrant (typically, a static member would do that). But, why make it so complicated when this will achieve the same:

Code: Select all

DateTimeFormatter::format(LocalDateTime(), "%Y-%m-%d %H:%M:%S.%i");

And then, last but not least, the most recent release was 1.4.3, with 1.4.4 being released within a matter of days. Perhaps an upgrade would be a good idea ...
