 *  @brief Test driver for psTime functions
 *
 *  This test driver contains the following tests for psTime:
 *     1) Allocate psTime structure
 *     2) Get current time
 *     3) Get UT1 UTC delta
 *     4) Convert psTime to MJD
 *     5) Convert psTime to JD
 *     6) Convert psTime to ISO
 *     7) Convert psTime to timeval
 *     8) Create psTime from MJD
 *     9) Create psTime from JD
 *    10) Create psTime from ISO
 *    11) Create psTime from timeval
 *    12) Create psTime from TM
 *    13) Convert time between different types
 *
 *     O) Convert psTime time to LMST
