Using spdlog, how can I change the default rolling time of the daily logger?
In the following example, the rolling happens only at midnight:
auto logger = spd::daily_logger_st("my_logger", "fl_log.txt");
Currently there is no direct way to change the rotation time in the daily logger - please open an issue here..
A quick workaround would be to modify the _calc_midnight_tp()
function to return the desired rotation time instead of midnight in the daily_file_sink class..
For example to rotate in 1am instead of midnight:
static std::chrono::system_clock::time_point _calc_midnight_tp()
{
using namespace std::chrono;
auto now = system_clock::now();
time_t tnow = std::chrono::system_clock::to_time_t(now);
tm date = spdlog::details::os::localtime(tnow);
date.tm_min = date.tm_sec = 0;
date.tm_hour = 1;
auto rotate_time = std::chrono::system_clock::from_time_t(std::mktime(&date));
return system_clock::time_point(rotate_time + hours(24));
}
Edit: I committed a fix to this issue. Now user can set HH:MM of the desired rolling time
