Possible 2038 bug in credentials cache api

[William Brown]

Hi there,

https://github.com/krb5/krb5/blob/master/src/include/CredentialsCache.h#L379

It appears that cc_time_t is a cc_uint32 which leads me to believe that users of this interface may fall into a yr 2038 bug by treating this as an int32t. What would be the best way to get this fixed in the various users/providers of this api?
