Member Function Documentation

buildTimeInfo()

struct::tm * el::base::utils::DateTime::buildTimeInfo ( struct timeval * currTime, struct ::tm * timeInfo )

static

formatTime()

base::type::string_t el::base::utils::DateTime::formatTime ( unsigned long long time, base::TimestampUnit timestampUnit )

static

Formats time to get unit accordingly, units like second if > 1000 or minutes if > 60000 etc.

getDateTime()

std::string el::base::utils::DateTime::getDateTime ( const char * format, const base::SubsecondPrecision * ssPrec )

static

Gets current date and time with a subsecond part.

Parameters

format	User provided date/time format
ssPrec	A pointer to base::SubsecondPrecision from configuration (non-null)

Returns

string based date time in specified format.

getTimeDifference()

unsigned long long el::base::utils::DateTime::getTimeDifference ( const struct timeval & endTime, const struct timeval & startTime, base::TimestampUnit timestampUnit )

static

Gets time difference in milli/micro second depending on timestampUnit.

gettimeofday()

void el::base::utils::DateTime::gettimeofday ( struct timeval * tv )

static

Cross platform gettimeofday for Windows and unix platform. This can be used to determine current microsecond.

@detail For unix system it uses gettimeofday(timeval*, timezone*) and for Windows, a seperate implementation is provided

Parameters

[in,out]

tv

Pointer that gets updated

parseFormat()

char * el::base::utils::DateTime::parseFormat ( char * buf, std::size_t bufSz, const char * format, const struct tm * tInfo, std::size_t msec, const base::SubsecondPrecision * ssPrec )

staticprivate

timevalToString()

std::string el::base::utils::DateTime::timevalToString ( struct timeval tval, const char * format, const el::base::SubsecondPrecision * ssPrec )

static

Converts timeval (struct from ctime) to string using specified format and subsecond precision.
