IBT. / NBT. Conditional Statement
If Before Timestamp / If NOT Before Timestamp
Intention
What is a TimestamP
A Timestamp is a Time-Value in the Format: HH:MM:SS or HH:MM:SS.mmm
Using the TCA. and these other Time-Stamp Commands you can work with Timestamps.
IBT. will need two timestamps as Parameter. It will then compare both Timestamps and decide
if Timestamp P1 is BEFORE Timestamp P2.
If Timestamp P1 is equal to Timestamp P2 then the time P1 is NOT BEFORE P2.
If you specify an @ Sign in front of P1 then the statement will evaluate if P1 = P2 means If Timestamp 1 is equal to Timestamp 2 instead.
In case of an error, the IBT. will by default evaluate to true, but will raise an error on TOS.
Hint: $time$ will return a timestamp like: 12:01:40
If one or both Parameters include ".000" Microseconds, then these will also be evaluated.
If Microseconds are missing, they will be ignored.
The negative Form of this statement is NBT.
Now here is the special Mode using the @ Operator.
And finally.
Syntax
IBT.[@]P1|P2 ... ELS. ... EIF.
NBT.[@]P1|P2 ... ELS. ... EIF.
Parameter Explanation
P1 - Timestamp 1 that needs to be AFTER P2 for this to evaluate to TRUE.
If you specify an @ Sign in front of P1 then the statement will evaluate if P1 = P2 means If Timestamp 1 is equal to Timestamp 2 instead.
P2 - Timestamp 2
