Fixes #54723
Prior to this patch, the timestamp part in the profile filenames was
using go format
.999
for the millisecond part. However,.999
causes the millisecond part to be omitted entirely if they happen to
be zero. The correct format was in fact
.000
.Release note (bug fix): The file names for generated goroutine, CPU
and memory profiles were sometimes incorrect, resulting in repeated
warnings like
strconv.ParseUint: parsing "txt": invalid syntax
inlog files. This has been corrected.
