What the specification says

Indicates how long the order as specified in the side stays in effect. SideTimeInForce allows a two-sided cross order to specify order behavior separately for each side. Absence of this field indicates that TimeInForce should be referenced. SideTimeInForce will override TimeInForce if both are provided.

Descriptions are quoted from the FIX Orchestra sources under the Apache 2.0 licence.

Edit and decode it yourself

Shown with | separators for readability. On the wire FIX uses SOH (0x01), an invisible control byte — and because BodyLength and CheckSum are computed over the actual bytes, the two forms have different checksums. Both are valid and both decode here.

Where tag 962 appears

Requiredness is a property of the message, not of the field: the same tag can be optional in one message and conditionally required in another.

Wire format

A UTC date and time. The fractional-seconds part is optional, so two timestamps can be equal but not byte-identical. @boarteam/fix keeps the value as a string; format rules are checked by validate(), which reports validate/invalid-value rather than throwing.

Decode this in your own code

The same engine that produced the decoded example above is an Apache-2.0 npm package with zero runtime dependencies. It runs in Node and in the browser, and parse() returns problems as data instead of throwing.
