Yes, the values are there, but babeltrace cannot deduce the clock

Okay. The timestamp_begin and timestamp_end member in packet.context are
for the whole recording process.
The timestamp_begin means first record item recorded in the whole
process per CPU.
The timestamp_end means the last record item recorded in the whole
process per CPU.
So I moved the timestamp value of individual record item in event.header
https://github.com/rmeena840/rtems-tools/commit/0542b83c5f28ad2d005e8c0d86c0f4a13d43fee9
Now, babeltrace is able to print timestamp value now.
It looks like this:
babeltrace . | head

Very good, please change now the format of the event header to the one
used by LTTNG:
struct event_header_compact {
enum : uint5_t { compact = 0 ... 30, extended = 31 } id;
variant <id> {
struct {
uint27_clock_monotonic_t timestamp;
} compact;
struct {
uint32_t id;
uint64_clock_monotonic_t timestamp;
} extended;
} v;
} align(8);
