This command is used to convert a time value formatted as a timestamp, "YYYY-MM-DD HH:MM:SS[.[u]+]" to a six element vector {years months days hours minutes seconds}. The timestamp can have arbitrary single characters separating the year, month, day, and hours, but the usual zero-padded numeric values must be supplied. If the conversion cannot be done, an empty result is returned.
The command is part of the Humelib package and can be imported from the namespace humelib.
package require Humelib
namespace import -force humelib::*
set v1 [timestamp_to_tv "2002-12-25 08:09:10"]
set v2 [timestamp_to_tv "2002/12/25T08:09:10.123456"]
if { $v1 != $v2 } { error "should be equal"}
