TIME: current time and date, convert times and dates, calendar functions (H)

Optional keywords:

The explicit result of TIME is always the number of seconds elapsed since midnight
- sec_since_midnite = TIME( options ) ! e.g. 86399.000 at 23:59:59
TO
: elements left of keyword "TO" are converted to the optional variables right of "TO", like
- TIME(YYYYMMDD=19991231, TO, Excel=x) ! x is set to 36525
If TO is the first keyword, the current date and time become the default
- TIME(TO, YYYYMMDD=text) ! e.g. "20080728123920.567"
To measure the time passed between calls:
- tstart = TIME()
- seconds_elapsed = TIME() - tstart
