strftime equivalent in c++
HI,
i wish to convert a millsec value to a readable string format.
the one option is to use strftime.
However this is a bit costly (1-5 micros).
is there a a faster way to do so with just string manipulation
(Note i have the date object which has the time details but wish o avoid strftime)

Not unless you keep a record of past present and future cal years...things like weekday monthday yearday year month day leap years etc etc...which is no easy thing to track for a programmer. The kernel maintains that for you so doing it yourself would be costlier and laborious.

If there were a faster way to do strftime, strftime would probably be doing it... (As an aside, "C++" doesn't usually mean "faster".)

If it needs to be done thousands of times per second, why bother with strftime, no human can read it that fast, just store time in microseconds.
