D struct_TM Like(tm)
The first parameter is an initialized TM structure. That value in the TM
structure is converted into a time_t integer value, and returned.
Use this procedure to translate a TM structure into a TM value. This allows a more familiar TM structure to be initialized through whatever means necessary, and then convert that value to a TIME_T value that is used by various other time-related procedures.
