Cron job finish log shows raw format string instead of formatted duration

[thzgajendra]

Description

When a cron job finishes, the log message shows the duration with a raw Go format string instead of a properly formatted value:

INFO [13:47:40] Finished cron job: gcp-db-migration in %!s(float64=0.000134084)

Expected output should be something like:

INFO [13:47:40] Finished cron job: gcp-db-migration in 0.000134s

Root Cause

The log line is likely using %s format verb for a float64 duration value, which produces the %!s(float64=...) output. It should use %f, %v, or format it as a time.Duration string.

Steps to Reproduce

1. Register any cron job with app.AddCronJob(...)
2. Let it execute
3. Observe the "Finished cron job" log line — duration is displayed as %!s(float64=X.XXX)

GoFr Version

v1.54.5

Update: This bug exists in v1.54.5 where time.Since(start).Seconds() (returns float64) is logged with %s format verb:

// v1.54.5 — buggy
duration := time.Since(start).Seconds()  // float64
c.Infof("Finished cron job: %s in %s", j.name, duration)  // %s on float64 → %!s(float64=...)

The development branch already has the correct code (commit 9f940ff6) which uses time.Since(start) directly (returns time.Duration with proper String() method):

// development — correct
c.Infof("Finished cron job: %s in %s", j.name, time.Since(start))

This fix should be included in the next release.
