|
// NOTES:
|
|
// 1. gmtime, mktime, and localtime all use a single statically allocated tm structure
|
|
// for the conversion. Each call to one of these routines destroys the result of the
|
|
// previous call. Obviously, that's not threadsafe.
|
|
// 2. Right now this only deals with localtime, because we're not using the other 2 fns.
|
|
// If we need to use gmtime or mktime, they'll need to be built analogously, using the
|
|
// same mutex.
|
|
// 3. _tasctime uses a single, statically allocated buffer to hold its return string.
|
|
// Each call to this function destroys the result of the previous call.
