◆ convert_secs_to_formatted_string()

std::string oomph::TimingHelpers::convert_secs_to_formatted_string ( const double & time_in_sec )

Returns a nicely formatted string from an input time in seconds; the format depends on the size of time, e.g.: 86510 will be printed as 1d 1m:50 3710 will be printed as 1h:01:50 700 will be printed as 11m:40 59 will be printed as 59s
