d$ = TimestampToDate(s[, unixtime])
dd-mmm-yyyy hh:mm:ss. See CompareStr for details.
The optional argument unixtime specifies whether or not the timestamp is measured
from the beginning of the Unix epoch (i.e. January 1st, 1970, 00:00:00 UTC) or from the
time when Hollywood was started. By default, timestamps are measured from the time
when Hollywood was started.
To convert a date back into a timestamp, use the DateToTimestamp() function. See DateToTimestamp for details.
True the timestamp is interpreted as relative
to the beginning of the Unix epoch; otherwise it is relative to the time
when Hollywood was started (defaults to False)
