Classes
class	nidas::util::UTime
	A class for parsing, formatting and doing operations on time, based on Unix time conventions, where leap seconds are ignored, so that there are always 60 seconds in a minute, 3600 seconds in an hour and 86400 seconds in a day. More...
class	nidas::util::UTime_stream_manip< charT >
	class for changing output format of UTime on ostream, in a way like the standard stream manipulator classes. More...

Namespaces
namespace	nidas
	Root namespace for the NCAR In-Situ Data Acquisition Software.
namespace	nidas::util
	General utility classes. nidas::util contains classes of general utility, like Socket, Thread, etc. The classes use only the standard Unix system libraries and libstdc++, and have no dependency on other external packages such as an XML parser, or a logging package.

Functions

template<typename charT >
UTime_stream_manip< charT >	nidas::util::setDefaultFormat (const std::string &val)
	Function to set the default UTime output format on an ostream.
template<typename charT >
UTime_stream_manip< charT >	nidas::util::setTZ (const std::string &val)
	Function to set the UTime timezone on an ostream.
long long	nidas::util::getSystemTime ()
	Return the current unix system time, in microseconds since Jan 1, 1970, 00:00 GMT.
long long	nidas::util::timeCeiling (long long t, long long delta)
	Return smallest time that is an integral multiple of delta, that isn't less than or equal to argument t.
long long	nidas::util::timeFloor (long long t, long long delta)
	Return largest time that is an integral multiple of delta, that isn't greater than argument t.
bool	nidas::util::sleepUntil (unsigned int periodMsec, unsigned int offsetMsec=0)
	Utility function, sleeps until the next even period + offset.
