check_msg_time: Check the time value(s) at a specific message

Description

check_msg_time examines the time point of a specific Sample Message for each event. Depending on the format of the data, it will use one of three columns: TIMESTAMP, Align, or Time. If times at which the message occurs are equal, it will return a single value. Optionally, the result can be output to a dataframe containing all event-level information.

Arguments

Msg	A character string containing the exact message to be found in the column SAMPLE_MESSAGE or a regular expression for locating the appropriate message.
ReturnData	A logical indicating whether to return a data table containing Message Time information for each event.

Value

The value(s) of Time (in milliseconds) at which the Sample Message is found.
