◆ getCurrentTime()

TimeRecord TimeRecord::getCurrentTime ( bool  Start = true)
static

Get the current time and memory usage.

If Start is true we get the memory usage before the time, otherwise we get time before memory usage. This matters if the time to get the memory usage is significant and shouldn't be counted as part of a duration.
