InsertWallclock
Inserts the system clock as a message header.
Use InsertWallclockHeaders SMT if you want to use more than one date time part. This avoids multiple SMTs and is more efficient.
For example, if you want to partition the data by yyyy-MM-dd/HH, then you can use InsertWallclockHeaders which inserts multiple headers: date, year, month, day, hour, minute, second.
Inserts the system clock as a message header, with a value of type STRING. The value can be either a string representation of the date and time epoch value, or a string representation of the date and time in the format specified for example yyyy-MM-dd HH:mm:ss.SSS.
