Bug when converting syncprov-checkpoint to olcSpCheckpoint?

I am experiencing unexpected results when converting the
syncprov-checkpoint option in file-based configuration to the
olcSpCheckpoint attribute in online configuration.

To reproduce the unexpected results:

1.  Configure OpenLDAP using file-based configuration that contains the
following line:

syncprov-checkpoint 100 10

2.  Convert file-based configuration to online configuration using the
following command:

slapd -f slapd.conf -F slapd.d

My file-based configuration is converted to the cn=config database, but
after conversion the value of the olcSpCheckpoint attribute in the
olcOverlay={1}syncprov,olcDatabase={1}bdb,cn=config entry is "100 600"
when I expect it to be the same as in my file-based configuration ("100
10").

Is this a bug or does the olcSpCheckpoint attribute use different units
(seconds) than the syncprov-checkpoint option (minutes)?
