TIME Instruction

TIME t [#]

If the time t (measured in seconds from the start of the job) is exceeded, SHELXL_93 performs no further least-squares cycles, but goes on to the final structure factor calculation followed by bond lengths, Fourier calculations etc. The default value of t is installation dependent, and is either set to 'infinity' or to a little less than the maximum time allocation for a particular class of job. Usually t is 'CPU time', but on some simpler computer systems (e.g. PC's) the elapsed time may have to be used instead.
