Tme Functons
The table below shows the functions related to time. The functions are not case sensitive.
Only integer numeric constants can be written in the function parameters <year>,
<month>, <day>, <hours>, and <minutes> in the table below. The terminology used in
the description in the table are defined below.
Edge:
Returns 1.0 for computation immediately after the specified absolute or
relative time.
Previous edge: Returns 1.0 for computation immediately before the specified absolute or
relative time.
Level: Returns 1.0 during the specified absolute time or relative time.
• Selectable range of parameters
<years>: 1970 to 2036
<month>: 1 to 12 (1: January, 2: February, ..., 12: December)
<day>: 1 to 31
<week day>: 0 to 6 (0: Sunday, 1: Monday, ..., 6: Saturday)
<hours>:
0 to 23
<minutes>: 0 to 59
