Time Conversion
The operators convert time values (TIME or LIME) into the specified data types and return this type-converted value.
Call syntax: <TIME_TO<target type> ( <operand> ), <LTIME_TO<target type> ( <operand> )
Operand | Data Type | Description |
|---|---|---|
Variable or literal |

Operator | Operator | Example | Return Value | Description |

|
| LTIME_TO_DATE(LTIME#2us1ns); |
| Syntax: D#yyyy-MM-dd |

| TIME_TO_DT(T#5d4h3m2s1ms); LTIME_TO_DT(LTIME#2us1ns); |
| Syntax: DT#yyyy-MM-dd-hh:mm:ss |

|
| TIME_TO_STRING(T#0MS); |
| Important: The typed value is left-aligned as a character string and truncated if it is too long. Therefore, declare the return variable long enough that the string has enough space without any manipulation. |
